Question

Which, when dissolved in diethyl ether, will extract into aqueous sodium hydroxide? I and II III only I, II, and III II and III When hexane and an aqueous solution are mixed in a separatory funnel, hexane will mix completely with the aqueous solution and one layer will be present in the funnel. hexane will not mix with the aqueous solution and hexane will be found as the lower liquid layer in the funnel. hexane will not mix with the aqueous solution and hexane will be found as the upper liquid layer in the funnel. hexane will react with the water in the aqueous solution forming an alcohol. Which of these C_4H_8O isomers should have the highest boiling point? Identify the weakest acid. Which of these is a Lewis acid? Identify the strongest base. Which projection represents the most stable conformation of (CH_3)_2 CHCH(CH_3)_2 The most stable conformation of cis 3-ehtyl-1-isopropylcyclohexane is represented by: Give the configurations of centers a and b (in that order). R, R R, S S, S S, R

Explanation / Answer

8. answer: D

both alchol and carboxylicacids reacts with base.

9. answer: C

hexane is non-polar and aqueous is polar. so that , aqueous is present at lower layer.

10. answer: A

alcohol is stabilised by hydrogen bonding.so that boiling point is higher.

11. answer: C

-CH3 is a +I group. so that acidity decreases.

12. answer: A

   all carocations are lewis acids.

13. answer: A

aliphatic amines are more basic than aromatic amines.
