1.	Which of the following has larger dipole moment ? Explain . 1-Butyne or 1-Butene
Answer» Solution :Their strcutures are : `H_(3) underset("1-Butyne")(C-CH_(2) - C-=C-H)` In 1-Butyne , each triply bondedC-atom is SP -hybridized whereas in 1-Butene, each doubly bonded C-atom is `sp^(2)` -hybridized . Hence 1-Butyne has LARGER dipole MOMENT because the electronegativity of sp-C is more than that of `sp^(2) - C`
