What classification of alcohol would be synthesized from the reaction of 2-butanone with a Grignard reagent? From the reaction of butanal with a Grignard reagent?A. A secondary alcohol; a secondary alcoholB. A tertiary alcohol; a secondary alcoholC. A secondary alcohol; a primary alcoholD. A tertiary alcohol; a primary alcohol

B. A tertiary alcohol; a secondary alcohol

Explanation:

Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl group.

Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary)  varies depending on which it reacts with.

2-butanone is a ketone.

Ketones reacts with Grignard reagent to form tertiary alcohol

Butanal is an aldehyde.

Aldeyde reacts with grignard reagent to form Secondary alcohol

The answer is; Tertiary alcohol; Secondary alcohol

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
