What are the atomic orbitals used in the double part of the double bond If the C-C axis of the given molecule is the y axis, and the x axis is up and down in the plane of the paper,?
As a bromine molecule approaches perpendicular to the negatively charged pi cloud of the carbon-carbon double bond, its bonding electrons are repelled away from the bromine atom nearer the double bond
Compound A, C6H10O2, is optically active. It dissolves slowly in aqueous NaOH, consuming one equivalent of base. When the solution is acidified, A is slowly regenerated.
