What order or C-H bond lengths do you expect in `C_(2) H_(6), C_(2) H_(4) and C_(2) H_(2)` and why ? |

Answer» ` C - H (C_(2) H_(6)) gt C - H (C_(2) H_(4)) gt C - H (C_(2) H_(2)) ` . This is because hybrid orbrid ordbitals of carbon involved in overlapping with 1s orbital of hydrogen are `sp^(3) gt sp^(2) gt sp` and ap respecitvely and their sizes are in the order ` sp^(3) gt sp^(2) gt sp ` . |
