Which structure shows the correct electron arrangement in CCl4?
A
A central upper C is single bonded to upper H above, below, and to the left, and single-bonded to upper C l to the right. The C l has three pairs of electron dots, above, right, and below.
B
A central upper C is single bonded to upper C l to the top, bottom, and left; those upper C l atoms have three pairs of electron dots on the sides away from the bond. The C is also single bonded to an upper H to the right.
C
A central upper C is single bonded to upper H above and below, and to upper C l to the left and right. The C l have three pairs of dots, above, below, and to the side opposite the bond.
D
A central upper C is single bonded to upper C l above, right, left, and below. All the C l atoms have 3 pair of electron dots, on the three sides that do not have the bond.
