So for this question, we have ethylene oxide.
00:03
And for part a, we are asked, the expected bond angles in the ring.
00:09
So that's these three angles here.
00:13
Now, this forms a pretty symmetrical triangle.
00:17
So the bond angles are going to be approximately 60 degrees.
00:21
And that goes for the three of these angles are all going to be equal, and we're going to be 60 degrees.
00:27
Since if we have a equilateral triangle where all the angles are the same, they each have to be 60, so that the sum of all the angles is 180 in a triangle.
00:39
For part b, we are asked the hybridization of the atoms in the ring.
00:48
So starting with the first carbon here, this will be carbon 1, this will be carbon 2.
00:54
Carbon 1 has a hybridization of sp3, since it bonds with...
01:00
Four atoms, makes four bonds...
