NEET 2026 Chapter-Wise Weightage For Chemistry

Scoring full marks in chemistry is possible when a candidate knows what his/her weaker section is and what’s the weightage of that particular section. The NEET Chemistry syllabus includes chapters from organic, inorganic, and Physical chemistry. Candidates can refer to the table below to know NEET chapter-wise weightage for Chemistry to prepare well for the NEET 2026 exam.

NEET 2026 Chemistry Syllabus With Weightage

The syllabus of NEET Chemistry is divided into Physical, Organic, and Inorganic Chemistry, with varying levels of focus across different chapters. The following table gives topic-wise weightage as per an analysis of NEET question papers of last five years. This analysis will help candidates to adopt a smart and strategic study plan.

The data is from past five years and chapters States of Matter, Hydrogen, The s-Block Element, Solid State, Surface Chemistry, Polymers, Environmental Chemistry, General Principles and Processes of Isolation of Elements are not in the NEET syllabus now

Frequently Asked Questions in NEET Chemistry

Given below are the important NEET chemistry questions asked in the exam. Candidates must read further to know more about the repeatedly asked questions in NEET Chemistry.

Question: If the rate constant for a first-order reaction is k, the time (t) required for the completion of 99 of the reaction is given by:

Option 1: $t = 0.693k$

Option 2: $t = 6.909k$

Option 3: $t = 4.606k$

Option 4: $t = 2.303k$

Answer: $t = 4.606k$

Solution:

The integrated rate law for a first-order reaction is given by:
$t = \dfrac{2.303}{k}\log_{10}!\left(\dfrac{a}{a - x}\right)$.

Given: $a = 100$, $x = 99$, hence $a - x = 1$.

Substituting these values:
$t = \dfrac{2.303}{k}\log_{10}!\left(\dfrac{100}{1}\right)$.

Since $\log_{10}(100) = 2$,

$t = \dfrac{2.303 \times 2}{k} = \dfrac{4.606}{k}$.

Thus, the time required for $99%$ completion is $t = \dfrac{4.606}{k}$.

Question: The correct order of atomic radii in group 13 elements is:

Option 1:

B < Ga < Al < Tl < In

Option 2:

B < Al < Ga < In < Tl

Option 3:

B < AI < In < Ga < Tl

Option 4:

B < Ga < Al < In < Tl

Answer: B < Ga < Al < In < Tl

Solution:

As we learnt in the topic of Ionisation Energy of the Boron Family:

It does not decrease regularly down the group.

This is because there is a discontinuity between Al and Ga, and between In and Tl, due to the inability of d and f electrons (which have a low screening effect) to effectively compensate for the increase in nuclear charge.

In Group 13, the trend in atomic radius is also not regular due to transition contraction.

Hence, option number (4) is correct.
