1S. N.N-diethyl-m-tolumide (DEET) is the active ingredient in many mosquioreof DEET is the hybridization state of carbon indicated by the arrow in shown below? ts. What the CHy CH2 16. The orbital diagram for a ground-state oxygen atom is ls 2s 2p A) B) C) D) E) 11 11L1 Solution 15) B) sp2 When a carbon atom bound to three atoms (two single bonds, one double bond) is sp 2 hybridized. When carbon is bonded to four other atoms (with no lone electron pairs), the hybridization is sp 3 The third possible arrangement for carbon is sp hybridization which occurs when carbon is bound to two other atoms (two double bonds or one single + one triple bond) 16) Answer : (D) Ground State Oxygen Atom: electron configuration is 1s 2 2s 2 2p 4 .
