Sapling Week 7/8 #18

Postby Melody Haratian 2J » Sun Dec 06, 2020 1:18 pm

Hi guys!
I’ve been having trouble understanding this part of question 18 from the Week 7/8 homework.
The question is “ A general formula for molecules of this type is H2C(C)xCH2, where x is a whole number.” Select the correct statement about the relationship of x to the orientations of the hydrogen atoms in such a molecule.
a. If x is an even number, all of the hydrogen atoms in that molecule will be coplanar.
b. If x is an odd number, all of the hydrogen atoms in that molecule will be coplanar.
c. There is no relationship between x and the relative orientations of hydrogen atoms in such a molecule”
What does it mean to be coplanar and how would you go about getting the answer to this problem?

Coplanar means to be in the same plane and if there are an even number of C's and H's the molecule will be coplanar, I believe.
