pH problems Organic chemistry problems IUPAC name for CH3CH2CH2CH double bond CHCH2COOH
Which exibits geometric isomerism
CH3C triple bond CHCH3CH2CH double bondCH2CH3CH double bond CHCH3
Compound A has the molecular formula C8H14. Addition of bromine to A gives a new compound B, with the formula C8H14Br4. Treatment of A with and aqueous acid gave only one product, a symmetricial diol (two alcohol groups) C, C8H18O2. C could not be oxidized with acidic permanganate. Deduce structures for A,B, and C
