I THINK it's 1,1-Difluorononane, or $C_9H_{18}F_2$ .

I'm not sure how to draw it and show you, but I will type it out and hopefully you will understand.

4-nonene means the double bond is the fourth possible one:
CH 3 - CH 2 - CH 2 - CH=CH-CH 2 - CH 2 - CH 2 - CH 3
adding F2 means F2 are added across the double bond
-> CH 3 - CH 2 - CH 2 - CHF-CHF-CHF- CH 2 - CH 2 - CH 2 - CH 3
So: C9H18+F2 --> C9H18F2

Indicate the peptides that would result from cleavage by the indicated reagent: a. Gly-Lys-Leu-Ala-Cys-Arg-Ala-Phe by trypsin b.

Answer:

a. Gly-Lys + Leu-Ala-Cys-Arg + Ala-Phe

b. Glu-Ala-Phe + Gly-Ala-Tyr

Explanation:

In this case, we have to remember which peptidic bonds can break each protease:

-) Trypsin

It breaks selectively the peptidic bond in the carbonyl group of lysine or arginine.

-) Chymotrypsin

It breaks selectively the peptidic bond in the carbonyl group of phenylalanine, tryptophan, or tyrosine.

With this in mind in "peptide a", the peptidic bonds that would be broken are the ones in the "Lis" and "Arg" (See figure 1).

In "peptide b", the peptidic bond that would be broken is the one in the "Phe" (See figure 2). The second amino acid that can be broken is tyrosine, but this amino acid is placed in the C terminal spot, therefore will not be involved in the hydrolysis.
