The `C -C` bond length is `1.54 Å C =C` bond length is `1.33 Å` What is the circumference of benzene ring ? Bond length between single and double bonds `= 1.4 Å` .A. `(3 xx 1.54 + 3 xx 1.33) Å`B. `(4 xx 1.54 + 2 xx 1.33) Å`C. `(6 xx 1.4)Å`D. `(4 xx 1.33 +2 xx 1.54)Å` |
Answer» Correct Answer - C Due to resonance the `C -C` bond length in benzyne is in between single and double bonds `1.4Å` Hence circumference ` = 6 xx 1.4 Å` . |
