Worked practice questions

As per your syllabus, the relative ELECTRONEGATIVITY of carbon hybridised as sp, sp², sp³ goes in which order?

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

Correct answer: C. sp > sp² > sp³

Your syllabus: greater s character ⇒ greater electronegativity. sp (50%) > sp² (33%) > sp³ (25%).

As per your syllabus, in CH₃-CH₂-CH₂-Br, the inductive effect is felt LEAST in which bond?

  1. C1-Br bond
  2. C2-C1 bond
  3. C2-H bond
  4. C3-H bond
Show answer and solution

Correct answer: D. C3-H bond

syllabus Problem 8.15: I-effect drops with bond distance. The C3-H bond is farthest from Br, so least affected.
