Question

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

Answer 1

Answer:

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

Answer 2

Answer:

It takes 30 minutes to feel the effects of alcohol.

Explanation:

It may take an hour to metabolize a drink, but it takes approximately thirty minutes before you feel alcohol's effects. This is a good gauge for pacing yourself. Drinking more than one drink every 30 minutes means you are probably drinking too much, too fast.
