Question

just need 17 explained

CO2H H- OH HOH CO2H He 17) How many asymmetric carbons are present in the compound below? 3-ethyl-2,2,4-trimethylpentane 18) Can the molecule shown below be properly described as a meso compound? No, because there has to be at least 2 Chiral centers. 19) Can the molecule shown below be properly described as a meso compound No, because it does not have plane of symmetry.

Answer 1

When a molecule has a carbon atom attached with four different groups or atoms are called asymmetric molecules.

C₃ carbon is an asymmetric carbon with four different groups.

CH₃ CH₂ CH3 СНа — С — сH — сH CH CH₃ CH3 3-ethyl, 2,2,4-trimethyl pentane (CH3) CH₂ CH3 - & - CH(CH3)2 four in it is (3 carbon has different groups same carbon so assymmetric carbon.
