For each of the following assume all lone pairs are shown.
(a) Determine the formal charge for the following.
nitrogen in A
Answer is not case sensitive.

carbon in B
Answer is not case sensitive.

carbon in C
Answer is not case sensitive.

boron in D
Answer is not case sensitive.
(b) Select the molecule(s) for which the central atom has access to an octet.

Your answer is incorrect.

Open the editor below and draw the skeletal structure, where each atom obeys the octet/duet rule and no atom possesses a formal charge, for the molecule whose condensed structure is below.

(a) (CH3)2CHCHCHC(CH3)3



(b) (CH3)3CC(CH3)2CHCHCH3


Remember for skeletal structures you do not show hydrogens that are bonded to carbon (hydrogens bonded to any other atom must be shown). Also, carbon labels are not used - carbons are understood to be at vertices and at the end of "sticks".

Give the IUPAC name for each of the following compounds.
Note: do not forget to use commas to separate locant numbers from each other and to use hyphens to separate locant numbers from letters.
a)

Answer is not case sensitive.
b)

Answer is not case sensitive.
c)

Answer is not case sensitive.
d) CH3(CH2)4CH3 (Hint: If you miss this one, see Table 2.4 p. 62 to make sure you are typing in the IUPAC name (not the common name).)
Answer is not case sensitive.
e) (CH3CH2)2CHCH2C(CH3)3
Answer is not case sensitive.
