Question

The approximate H-C-H band angle in CH_3^+ is a. 60 degree b. 90 degree c. 109 degree d. 120 degree e. 180 degree The Moline AX_3 in which a is the central atom is polar and obeys the octet rule therefore A has no long pairs b. A has no long pairs c has no long pairs When a carbon atom has sp hybridization it has four pi bonds b. three pi bonds and two sigma bonds d. one pi bonds and three sigma bonds e. four sigma bonds The hybridization of the central atom a molecule The bonding in ketene H_2 CCO, is best decreed as five sigma bonds four sigma bands two pi bonds fine pi bonds four sigma bonds and one pi bonds Which of the following electron configuration is Not permissible a. is ^2 2s^2 2P^3 is^2ss^2 2 p^6 is ^2 2s^2 p^2 e Is ^2 2S^3 2 P^6 3s^1

Explanation / Answer

Note that CH3+ will form a trigonal planar shape

since the positive charge will allow the hybridized overlaps to extend through the 2-Dimensional plane

therefore

the most stable form for Hydrogens in this plane are 120° each bond

so choose D from the list
