Mathematical Analysis of Cubic System
Coordination Number (C. No.)
In Simple Cubic (SC): 6
In Face Centered Cubic (FCC): 12
In Body Centered Cubic (BCC): 8
Density of Lattice Matter (d)
It is the ratio of mass per unit cell to the total volume of a unit cell and it is found out as follows.
Here, d = Density
Z = Number of atoms
N0 = Avogadro number
a3 = Volume
a = Edge length
To find the density of a unit cell in cm3, m must be taken in g/mole and should be in cm.
Radius Ratio
It is the ratio of the radius of an octahedral void to the radius of the sphere forming the close-packed arrangement Normally, ionic solids are more compact, as voids are also occupied by cation (smaller in size). The pattern of arrangements and type of voids both depend on the relative size (ionic size) of two ions in a solid.
For example, when r+ = r- the most probable and favourable arrangement is BCC type.
With the help of relative ionic radii, it is easier to predict the most probable arrangement. This property is expressed as radio ratio.
From the value of the radius ratio, it is clear that the larger the radius ratio, the larger the size of the cation, and the more anions needed to surround it—that is, the more coordination numbers.

Radius ratio for octahedron
Charge On Colloids
Colloidal particles always carry an electric charge. The nature of this charge is the same for all the particles in a given colloidal solution and may be either positive or negative.
Oxidation State
An interesting feature in the variability of oxidation states of the d-block elements is noticed among the groups. Although in the p–block the lower oxidation states are favoured by the heavier members (due to the inert pair effect), the opposite is true in the groups of d-block.

Preparation Of Aldehyde
Rosenmund Reduction
Stephen Reduction
Nucleophilic Addition Reaction:
(i) Mechanism of nucleophilic addition reactions:
Reduction And Oxidation Reaction
Reduction to hydrocarbons:
The carbonyl group of aldehydes and ketones is reduced to the CH2 group on treatment with zinc amalgam and concentrated hydrochloric acid (Clemmensen reduction) hydrazine hydrazone or with hydrazine, followed by heating with sodium or potassium hydroxide in a high boiling solvent such as ethylene glycol (Wolff-Kishner reduction).
Oxidation
Aldehydes differ from ketones in their oxidation reactions. Aldehydes are easily oxidised to carboxylic acids on treatment with common oxidising agents like nitric acid, potassium permanganate, potassium dichromate, etc. Even mild oxidising agents, mainly Tollens’ reagent and Fehlings’ reagent, also oxidise aldehydes.
Chemical Properties Of Carboxylic Acid:
Formation of Anhydride
Reaction with Ammonia
Reduction
Decarboxylation
Kolbe's electrolysis
Halogenation 
Ring substitution
Carbohydrates
Carbohydrates -
These are polyhydroxy aldehydes, ketones or substances that form these on hydrolysis and possess at least one chiral atom. The (-OH) group is available in the form of hemiacetals or hemiketals.
Classification:
Carbohydrates can be classified into three categories:
Monosaccharides: They are the simplest carbohydrates which cannot be hydrolysed into smaller molecules. They are sweet and crystalline and are called sugars.
Oligosaccharides: These carbohydrates, on hydrolysis, give two to nine molecules of monosaccharides classified as di-, tri, tetra-saccharides, etc. For example, sucrose, maltose, lactose, raffinose, etc. They are also called sugars.
Polysaccharides: These carbohydrates, on hydrolysis, give a large number of monosaccharides, e.g., starch, cellulose, etc. They are also called non-sugars.
Reducing and Non-reducing Sugars
Those sugars which reduce Fehling's and Tollens's solutions are called reducing sugars and those which do not reduce these reagents are called non-reducing sugars.

Hello student
Congratulations on your NEET 2024 score! With a rank of 71659 and a score of 605 marks in the GEN category with no reservation, your chances of getting a government BDS seat are possible, but it depends on various factors:
1. *Cutoff ranks*: Last year's cutoff ranks for government BDS seats varied across India, ranging from 30,000 to 1,50,000.
2. *Seat matrix*: The number of BDS seats available in government colleges and their distribution across states.
3. *State-wise counseling*: Counseling processes and seat allotment vary across states.
4. *Category-wise cutoffs*: GEN category cutoffs might be higher than reserved categories.
Based on previous years' trends, here are some possible scenarios:
- *Kerala*: You might get a government BDS seat in Kerala, as their cutoff ranks have been around 70,000-80,000 in previous years.
- *Tamil Nadu*: You have a chance in Tamil Nadu, where cutoff ranks have been around 60,000-70,000.
- *Other states*: In states like Maharashtra, Gujarat, or Rajasthan, the competition is higher, and cutoff ranks might be lower (around 40,000-50,000).
To increase your chances:
1. *Participate in state-wise counseling*: Register for counseling in multiple states to explore opportunities.
2. *Check seat matrices*: Look for states with a higher number of BDS seats in government colleges.
3. *Stay updated*: Monitor counseling schedules, cutoffs, and seat allotment lists regularly.
Remember, these are general insights based on previous years' trends. The actual cutoffs and seat allotment may vary. Best of luck!
Vaibhavi 26 July,2024
Hello aspirant,
The competition for medical seats, especially in private colleges, is extremely intense. Cutoff marks have been rising steadily over the years. To get a seat in a private medical college, you would generally need a score significantly higher than 425.
But, you should not lose hope here, instead, you can consider other healthcare-related fields like BDS, BAMS, BHMS, or paramedical courses. If you're determined to pursue MBBS, focus on improving your score for the next NEET exam.
Remember, it's essential to stay positive and explore alternative paths.
I hope this information helps you.

Hello aspirant,
While the exact cutoff for BAMS in CSMSS can fluctuate yearly based on various factors, a score of 478 is generally considered good for getting admission to a government Ayurveda college like CSMSS.
Factors Affecting Admission:
- Category: If you belong to a reserved category (SC, ST, OBC), your chances of getting a seat increase significantly.
- State Quota: Competition is generally lower for state quota seats compared to All India Quota seats.
-
Counseling Process:
Your final rank after the counseling process will determine your admission.
To increase your chances, you can participate in counselling or you can also explore other options too.
I hope this information helps.
