What is the relationship between the reactivity of alcohols with the length of the R-Group?

Answer 1

The active part of alcohols is their 'OH' group while alkyl group (carbon chain) remains in active so the increase in length of R' group decreases the reactivity of alcohol.h

Answer 2

The reactivity of alcohols generally decreases as the length of the R-group increases. This is due to steric hindrance caused by larger R-groups, which can hinder the approach of reagents to the alcohol functional group. Additionally, longer R-groups can stabilize the alkoxide ion formed during alcohol reactions, making the reaction less favorable.
