What is the idealizeddihedral angleof the H-N-C-F ? __________________________________(2pts)26a. During our last lecture we discussed that cyclohexane has two stable 3-D forms, a “chair” anda “boat”. Why is the “chair” more stable than “boat”? Note: At most two sentences will be read, besuccinct, get to the point.
