Q 1 :    

Compound A formed in the following reaction reacts with B gives the product C. Find out A and B.                 [2024]

  • A=CH3-C≡C-N+a,  B=CH3-CH2-CH2-Br

     

  • A=CH3-CH=CH2,  B=CH3-CH2-CH2-Br

     

  • A=CH3-CH2-CH3,  B=CH3-C≡CH

     

  • A=CH3-C≡C- +Na,  B=CH3-CH2-CH3

Q 2 :    

The incorrect statement regarding ethyne is                            [2024]

  • Both carbons are sp hybridised

     

  • The C − C bonds in ethyne is shorter than that in ethene

     

  • Ethyne is linear

     

  • The carbon-carbon bonds in ethyne is weaker than that in ethene

     

(4)

More are number of bonds between two atoms, shorter and stronger is the bond. Thus, carbon-carbon bond in ethyne is shorter and stronger than that of ethene.
