Question

Is the formation of methanal from alcohol a sn1 or sn2 pathway?

Answer 1

Heya!

This reaction follows an SN2 pathway. The nucleophile attacks and attaches partially to the carbon and after the transition state you get a mirror inverted product.

Thanks!

Answer 2

Explanation:

The first step of the reaction is the nucleophilic addition of Grignard reagent to the carbonyl group to form an adduct. Hydrolysis of the adduct yields an alcohol. ... You will notice that the reaction produces a primary alcohol with methanal, a secondary alcohol with other aldehydes and tertiary alcohol with ketones.

Thanks!❤
