Question

Propyne on polymerisation gives
(a) Mesitylene
(b) Benzene
(c) Ethyl benzene
(d) Propyl benzene

Answer 1

Polymerisation reaction of propyne in the presence of Red hot iron tube polymerises to give :- MESITYLENE .

Hope this helps...!!

Answer 2

Hey Dear,

◆ Answer -

(a) Mesitylene

● Explanation -

Three molecules of propyne polymerise to form 1,3,5-trimethyl benzene (mesitylene).

3 C3H4 --> C9H12

This trimerization can take place only in presence of red hot iron tube.

[Refer to the image for structure of mesitylene.]

# Uses of mesitylene -

• Mesitylene is used as a solvent for resins & gums.
• It's also used as ligand in organometallic compounds.
