Worked practice questions

As per your syllabus, the bond LENGTHS of single bonds formed by sp, sp², sp³ carbons go in which order?

  1. sp² < sp < sp³
  2. sp > sp² > sp³
  3. sp < sp² < sp³
  4. All equal
Show answer and solution

Correct answer: C. sp < sp² < sp³

Your syllabus: more s character pulls electrons closer to nucleus, giving shorter bonds. sp bonds are shortest.

As per your syllabus, in trivial nomenclature of disubstituted benzene, the prefix indicating 1,4-positions is which?

  1. cis
  2. para
  3. meta
  4. ortho
Show answer and solution

Correct answer: B. para

Your syllabus: ortho = 1,2; meta = 1,3; para = 1,4.

As per your syllabus, a species formed by homolysis with an unpaired electron is called which?

  1. Carbanion
  2. Free radical
  3. Nucleophile
  4. Carbocation
Show answer and solution

Correct answer: B. Free radical

Your syllabus: homolytic cleavage gives free radicals (single unpaired electron on each fragment).
