The National Testing Agency has successfully conducted JEE Main 2019 Paper 1 in 8 shifts (two shifts per day) between 9 and 12 January. The timing of first shift was 9:30 AM to 12:30 PM while second shift was from 2:30 PM to 5:30 PM. Here, we are providing JEE Main 2019 Memory Based Question and Topics shared by students who appeared for this exam. A total of 9,29,198 candidates registered for Paper I (which is for B.E/B. Tech aspirants). This is the first time, the JEE Main 2019 exam is being conducted in fully computer based test mode. The agency has already installed CCTV cameras and 4,000 jammers in order to stop cheating in the national exam.

JEE Main 2019: Analysis and Review 8 Jan (Paper II - All Shifts)
Few solved questions based on Topics asked in JEE Main Chemistry Paper are given below:
Question:
Considering the formation, breaking and strength of hydrogen bond, predict which of the following mixtures will show a positive deviation from Raoult's law?
(a) Methanol and acetone
(b) Chloroform and acetone
(c) Nitric acid and water
(d) Phenol and aniline
Solution: (a)
In pure methanol, molecules are hydrogen bonded. On adding acetone, its molecules get in between the host molecules and break some of the hydrogen bonds between them.
Therefore, the intermolecular attractive forces between the solute-solvent molecules are weaker than those between the solute-solute and solvent-solvent molecules.
On the other hand, other three remaining options will show negative deviation from Raoult's law where the intermolecular attractive forces between the solute-solvent molecules are stronger than those between the solute-solute and solvent-solvent molecules.
Question:
The molarity of a solution obtained by mixing 750 mL of 0.5 M HCl with 250 mL of 2 M HCl will be
(a) 0.875 M
(b) 1.00 M
(c) 1.75 M
(d) 0.0975 M
Solution: (a)
Let M be the molarity obtained on mixing
Question:
Question:
Which of the following curves is in according with Freundlich adsorption isotherm?
Solution: (c)
