Question

Write IUPAC names of the products
obtained by the reaction of cold
concentrated sulphuric acid followed by
water with the following compounds.
a. propene b. but-l-ene​

Answer 1

Answer:

1) CH2=CH-CH2 2)CH2=CH-CH2-CH3

Answer 2

The IUPAC names of the products obtained by the reaction of cold concentrated sulphuric acid followed by water with propene and but-1-ene​ are propan-2-ol and butan-2-ol respectively.

• The given reactions proceeds via first order substitution process (SN1).
• The first step in this process is the formation of carbocation followed by the attack of water molecule on the most stable carbocation obtained after any 1-2 shifts possible to form alcohol.
