To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.

C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.

F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.

As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.

Describe where the "Reference Carbon" (the one that determines if the structure is D or L) is located in a carbohydrate with mor

tresset_1 [31]

Answer:

Farthest from the carbonyl carbon.

Explanation:

Reference carbon that determined the absolute D and L configuration is located farthest from the carbonyl carbon.

In other words, reference carbon is that assymentric carbon which is located farthest from the carbolyl carbon and has configuration similar to D- or L-glyceraldehyde isomers.

D and L configuration is decided by the direction of -OH group attached to the reference carbon.

In L-isomer, -OH group is attached to the left side of the reference carbon and in D-isomer, -OH group is attached to the right side of the reference carbon.
