Multiple choice

Assertion: Addition of HBr to HC ≡ C − CH2 − CH = CH2 gives HC ≡ C − CH2 − CHBr − CH3 and not H2C = CBr − CH2 − CHBr − CH3. Reason: A triple bond is less reactive than a double bond.

  3. A is true but R is false.

  4. A is false but R is true.

  5. Both A and R are false.

A Correct answer
Explanation

This option is correct because chemically alkynes are very much like the alkenes. Both families are much more reactive than the alkanes. The carbon-carbon triple bond is less reactive than the carbon-carbon double bond toward some reactant like HBr.
