    This molecule has a Plane of symmetry and the molecule is rigid as well. Therefore the bridge head stereogenic center can't alter there stereo chemistry so it have one stereo isomer which is achiral (meso).

    Yes, both the bridgehead carbons are chiral with opposite configurations. Actually we call these type of compounds 'meso compounds'.

    yes sir

    eduncle-logo-app

    means only 2 chiral centre.. the top most we will not consider (which Is attach to ch3 and H)?

    eduncle-logo-app

    That is called psuedo asymmetric centre (same group but different configuration)

    This molecule has a plane of symmetry passing through carbon atom to which one H and one CH3 is attached and between the double bond. Therefore the molecule is achiral. No stereoisomers.

    yes sir it's not chiral.. but it can show stereoisomerism not optical active but it have.. so how many chiral centre are present.. I confused about bridge head carbon is it chiral centre?

    Yes both the bridgehead carbons are chiral with opposite configurations. Actually these type of compounds are called meso compounds.
