**Sun Nov 24, 2019 5:45 pm**For 2.45, can someone explain what the answers for e) and f) would be?

The question is:

Consider the molecules H2CCH2, H2CCCH2, and H2CCCCH2. (a) Draw Lewis structures for these molecules. (b) What is the hybridization at each C atom? (c) What type of bond connects the carbon atoms (single, double, etc.)? (d) What are the HCH, CCH, and CCC angles in these molecules? (e) Do all the hydrogen atoms lie in the same plane? (f) A generalized formula for molecules of this type is H2C(C)xCH2, where x is 0, 1, 2, etc. What can be said, if anything, about the relative orientation of the H atoms at the ends of the chain as a function of x?
