When hexane and an aqueous solution are mixed in a separator forced. (A) hexane

Question

When hexane and an aqueous solution are mixed in a separator forced. (A) hexane will mix completely with the aqueous solution and one layer will present in the funnel. (B) hexane will not mix with the aqueous solution and hexane will be found at the lower liquid layer in the funnel. (C) hexane will not mix with the aqueous solution and hexane will be found at the upper liquid layer in the funnel. (D) hexane will react with the war 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-ethyl-1-isopropyulclohexane is represented by: Give the configuration of corners a and b (in that order).

Explanation / Answer

(8) (b) Because of its acidic nature when NaOH is added it forms a soluble salt and enters into aqueous medium.

(9) (c) Hexane is not miscibel with water and found at upper layer becuase it is less denser than water.

(10) (A) Because of presence of -OH group which forms intermolecular hydrogen bonds.

(11) (c) Because of presence of electron donating methyl group.
