1. An alcohol is oxidized by chromic acid and does not react with Lucas reagent. What class of alcohol is it

The alcohol is a primary alcohol.

Explanation:

Chromic acid oxidizes primary alcohols to carboxylic acids and secondary alcohols to ketones but does not react with tertiary alcohols under mild conditions. Therefore, from the Chromic acid test, the class of alcohol is either primary or secondary.

Lucas reagent (a solution of anhydrous ZnCl₂ in conc. HCl)

Primary alcohols do not react readily at room temperature with the Lucas reagent, secondary alcohols react after some minutes while tertiary alcohols react immediately.

Since the alcohol is oxidized by chromic acid and does not react with Lucas reagent, it is a primary alcohol.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

0.88m hope i am correct : )
