How many products (including stereoisomers) are expected from monochlorination of the following compound?

Which one of the following compounds does not decolourize bromine water?

Which one of the following reactions does NOT belong to “Lassaigne’s test”?

Given below are two statements: Statement I : The boiling point of three isomeric pentanes follows the order n-pentane > isopentane > neopentane Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point. In the light of the above statements, choose the most appropriate answer from the options given below:
