Hi,

Hope you are doing well.

According to the NEET UG exam pattern, there will be 180 questions, 45 of which will be from the chemistry section. However, the CBSE has not provided a breakdown of the questions that will be asked in organic and inorganic chemistry. But the topics like carboxylic acid amynes aldehydes halogen carbons are very important. You can go with 1:1 ie 50-50 for organic and inorganic chemistry section.

Hope this helps.

Good Luck!
