To the best of my knowledge 1 is not true. The bond energy of cyclopropane and cyclobutane are higher that the others in that series.
2. The only planar cyclic hyrocarbon is cyclohexane. All of the others are puckered so none of the others are planar.
3. Cyclopropane has 60 degree angles.
4. Did you mean Alicyclic? If so yes. I think I learned in English class that placing an a in front of a word transformed it into no. If you mean acyclic (not cyclic) then there are no correct answers to the question. If you meant alicyclic then the answer is yes.
Which of the following statements about cycloalkanes is true?
1) The bonds in cyclopropane and cyclobutane are weaker than other cycloalkanes.
2) Most cycloalkanes are planar molecules.
3) Cyclopropane has 109° bond angles.
4) Cycloalkanes are also called "acyclic" compounds.
