In chemistry, a rotatable bond is a type of chemical bond that is not part of a ring structure and is attached to a non-terminal and non-hydrogen atom. This bond has the ability to rotate freely around its axis, which affects the overall shape and geometry of the molecule. In other words, a rotatable bond refers to any single bond that has the potential to rotate around its axis without breaking the bond.What is the number of bonds that can be rotated in the molecule?
