Question

Is this tetrahedral too? @surry99

Answer 1

or is it hexagonal?

Answer 2

i think its hexagonal

Answer 3

Each carbon in the ring has 3 unique directions so the bond angles for those are 120 degrees so all the elements in the ring lie in the same plane. The shape of the ring is a hexagon.
Now I am guessing the red element is oxygen...correct?

Answer 4

correct

Answer 5

So...would I can the shape hexagonal?

Answer 6

call^ not "can"

Answer 7

II would refer to the ring as hexagonal but lets talk about the -OH (called the hydroxyl group at the top) How many unique directions can you move from the oxygen...be careful with this one...

Answer 8

two?

Answer 9

is it a bent triatomic?

Answer 10

hint: are there any lone pairs of electrons on the oxygen?

Answer 11

yeah, one i think?

Answer 12

How would you determine of there are any lone pairs on the oxygen?
What rule must it follow?

Answer 13

According to the Octet rule it would have to have 2 lone pairs...that means four unique directions from the oxygen...therefore it would be based on a tetrahedron

Answer 14

octet rule.
one electron pair is connected tot he hydrogen, and one pair with the carbon, right? So, then two lone pairs?

Answer 15

yep

Answer 16

So...this shape would be both hexagonal and tetrahedral?

Answer 17

The way they are asking your questions is odd to me...
All the 6 carbon elements and their substituents lie in the ring ...so I would say the ring is
hexagonal. But as we have seen , we would expect the angles around the oxygen to be near 109.5 ...So the -OH group is not in the same plane as the ring.

Answer 18

Okay, thank you. :)

Answer 19

Have you discussed hybridization in class yet?

Answer 20

would i draw the structural formula like this:

?
