Question

How to prepare Alkenes from Alkanes?

Answer 1

Explanation:

Alkenes are generally prepared through β elimination reactions, in which two atoms on adjacent carbon atoms are removed, resulting in the formation of a double bond. Preparations include the dehydration of alcohols, the dehydrohalogenation of alkyl halides, and the dehalogenation of alkanes. Dehydration of alcohols.

Answer 2

Answer:

Explanation:

There are some methods,

for example we can do clorination and add an alcoholic base in order to undergo β elimination.. Look at the attachment for that

We can also prepare alkenes by converting alkanes to alkyl halides and then converting into alcohols and then converting them into alkenes look at the attachment again

these are some examples please mark me brainliest
