Question

Allyl carbocation is maor stable then n propyl carbocation

Answer 1

Answer: allyl carbocation

Explanation:

CH2CHCH2+ is more stable due to resonance. whereas there is no resonance in propyl carbocation

Answer 2

Answer:

2HC=CH-CH2+    >    3HC-CH2-CH2+

  allyl                            n propyl

Explanation:

Allyl carbocation is more stable due to resonance which increases its stability against n propyl carbocation having 2 H.C.
