Cyclopropane is a highly strained molecule. why? select all that apply.

Cyclopropane is a highly strained molecule because the conformations of the cycloalkanes are influenced by the torsional, angle strain, and steric strain. Cycloalkanes, which comprises more than three atoms of carbons are not flat molecules, they are puckered.  

The three and four-membered ring components exhibit angle strain and minimize the internal bond angles. The angle strain is generated when the bond angles deviate from the optimum tetrahedral angle, that is, 109.5 degree.  

Torsional strain is a resultant of eclipsing interactions, and steric strain is attained when the atoms are forced too close to each other.
