Question

Alkane molecules are not attacked by electrophiles or neutrophiles because they are:

• A. polar
• B. non-polar
• C. volatile
• D. unstable

Answer 1

Answer: (B)

non-polar

Electrophiles (positively charged species) and nucleophiles( negatively charged species) are positively and negatively charged radicals known as reagents which attack that site of an atom which is electron rich or electron deficient. Alkanes are non-polar saturated hydrocarbons in which shared pair of electrons are remain in the centre of the bond hence dipole moment is zero and the neutral compound is least reactive.
