IUPAC name for
CH3CH2CH2CH double bond CHCH2COOH

Which exhibits geometric isomerism

CH3C triple bond CH
CH3CH2CH double bondCH2
CH3CH 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 symmetrical diol (two alcohol groups) C, C8H18O2. C could not be oxidized with acidic permanganate. Deduce structures for A,B, and C

What is the pH of a solution containing 0.24 moles of ammonia and 17.8g of ammonium chloride, NH4Cl. Kb for ammonia is 1.8 times 10 Exp-5

What is the PH of a 0.085M solution of ammonium chloride. Kb for ammonia is 1.8 times 10 Exp-5

Calculate the pH fo a solution made by mixing 125ml of .200M HCl and 500 ml fo 0.0500M KOH

1. IUPAC name for CH3CH2CH2CH=CHCH2COOH = 3-heptenoic acid

2. Which exhibits geometric isomerism

CH3C CH: No, alkynes do not show geometric isomerism

CH3CH2CH=CH2; No, 1-butene has no geometric isomers because both methyl groups are on the same carbon.

CH3CH=CHCH3 : Yes

3. 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 an aqueous acid gave only one product, a symmetrical diol (two alcohol groups) C, C8H18O2. C could not be oxidized with acidic permanganate. Deduce structures for A, B ...
