Explanation

The correct ascending order of reactivity of alkyl halides is F, Cl, Br, I, with fluorine being the least reactive and iodine being the most reactive.

Reactivity increases down the group as bond strength decreases.

Explanation

In Friedel-Crafts acylation, an acyl group is introduced into the benzene ring in the presence of AlCl₃ (aluminum chloride).

It acts as a catalyst by facilitating the formation of the acylium ion that reacts with the benzene.

Explanation

Hydrocarbons do not have a tendency to form hydrogen bonding.

Because they lack highly electronegative atoms like oxygen or nitrogen that are necessary for hydrogen bonds.

In contrast, carboxylic acids, ammonia, and ethyl alcohol can all engage in hydrogen bonding due to their functional groups.

Explanation

To boil water at 110°C, the external pressure must be higher than normal atmospheric pressure (760 torr), typically in the range of 760 - 1200 torr. 

This increased pressure raises the boiling point of water above its standard boiling point of 100°C.
