Find out the statements which are not true. A. Resonating structures with more number of covalent bonds and lesser charge separation are more stable. B. In electromeric effect, an unsaturated system shows +E effect with nucleophile and -E effect with electrophile. C. Inductive effect is responsible for high melting point, boiling point and dipole moment of polar compounds. D. The greater the number of alkyl groups at

Options

  1. AB & D only
  2. BA, C & D only
  3. CB, D & E only
  4. DA, D & E only

Correct answer

A. B & D only

Step-by-step solution

Evaluating each statement: (A) TRUE - More covalent bonds with lesser charge separation increases resonance stabilization. (B) FALSE - In electromeric effect, unsaturated systems show +E effect toward nucleophiles and -E effect toward electrophiles, opposite to stated. (C) TRUE - Inductive effect of polar groups affects melting points, boiling points, and dipole moments. (D) FALSE - Greater alkyl substitution on doubly bonded carbons decreases heat of hydrogenation (more substituted alkenes are more stable). (E) TR
