Based on previous years' trends, the most important and high-scoring topics include Physical Chemistry (35–38%), Organic Chemistry (25–28%), and Inorganic Chemistry (25–28%). Additionally, Analytical Chemistry & Instrumentation (5–7%) and General Aptitude (15%) play a significant role in your overall score.

The Graduate Aptitude Test in Engineering, or GATE exam, is an all-India level exam, conducted annually at various exam centres across India. If you want to score above 65 marks in the GATE 2026 Chemistry exam, then this article is for you. In this article, we have covered the topic-wise estimated weightage for Chemistry and high-scoring Chemistry topics for the GATE 2026 exam in detail. 

High-Scoring Chemistry Topics in GATE 2026

Thermodynamics, chemical bonding, chemical kinetics, and organic reaction mechanisms are some of the high-scoring chemistry topics for GATE 2026. Over the past five years, these topics collectively account for around 43-45% of the GATE Chemistry 2026 exam.

Physical Chemistry

The branch of study that focuses mainly on the principles of thermodynamics, quantum and statistical mechanics is called Physical Chemistry. 

• The combination of Chemistry and Physics concepts can be applied in the numerical problems of Physical Chemistry. 
• With the help of Physics, you can understand the molecular behaviour of elements, molecules, and compounds. 

Organic Chemistry

The carbon-containing compounds are mainly called Organic compounds. Their properties and reaction mechanisms are studied in the field of organic chemistry. 

• The role of organic chemistry can be seen in our daily lives, from the use of medicines to cooking food. 
• This branch of chemistry focuses on the key topics such as structure, properties, synthesis, and reactions of carbon and its compounds. 

Inorganic Chemistry

The branch of chemistry that deals with the study of elements and their compounds, other than carbon-based compounds, is called inorganic chemistry. With a weightage of 25-28% in the GATE exam, it becomes one of the important topics that one should not skip. Since it is a high-scoring Chemistry subject for the GATE 2026 exam, some of the important subdisciplines involved in inorganic chemistry are:

• Coordination compounds 
• Periodic classification 
• Solid state, and
• Properties of metals and nonmetals.

Instrumentation Chemistry 

The branch of Chemistry that focuses on qualitative and quantitative analysis of substances using classical and instrumental methods is covered under Instrumental Chemistry. Some of the important techniques that are useful for practical applications in this field are as follows: 

• Spectroscopy, 
• Chromatography and 
• Electrochemistry

General Aptitude 

 The General Aptitude paper covers verbal and numerical skills and analytical thinking in the GATE exam, which is common for all GATE papers. It contributes a significant weightage to the exam. This section can be a plus point for those who have a strong grasp of accuracy and speed. The subtopics of General Aptitude include: 

• English Comprehension & Grammar
• Basic Maths 
• Data Interpretation 

Note: With daily practice of English comprehension, basic mathematics, and data interpretation questions, you can score full marks and keep yourself ahead of other students in the GATE 2026 Chemistry exam.

Engineering Mathematics

Engineering Mathematics is a field of applied mathematics that deals with mathematical models and techniques. 

These topics are helpful in modeling and problem-solving applications in biotechnology. Engineering Mathematics can be considered a high-scoring Chemistry topic for the GATE 2026 exam. 

GATE 2026 Topic-Wise Estimated Weightage for Chemistry

The GATE 2026 weightage for Chemistry is expected to be the same as the past year's exam trends. The topics like Physical and Organic Chemistry contribute a major percentage to the GATE 2026 Chemistry exam. This share is followed by Inorganic Chemistry and General Aptitude. Here is the detailed GATE 2026 topics-wise Estimated Weightage for Chemistry mentioned below in the tabular format:
