Methylene bridge

Index Methylene bridge

In organic chemistry, a methylene bridge, methylene spacer, or methanediyl group is any part of a molecule with formula --; namely, a carbon atom bound to two hydrogen atoms and connected by single bonds to two other distinct atoms in the rest of the molecule. [1]
