Answer 2

The alkane that gives only one mono-chloro product on chlorination in presence of diffused sunlight is neopentane (option-3).

• The IUPAC name of neopentane is 2,2-dimethyl propane.
• Its longest carbon chain is of 3 carbons.
• At carbon-2 two methyl groups are attached.
• On chlorination in presence of sunlight, it gives the mono-chloro product.
• Because in neopentane, all the hydrogen atoms act as primary hydrogen.
• Therefore, on chlorination with chlorine, it gives only one mono-chloro product.
