Since, there is no specification about the exact question to be answered, the first four questions are answered here, as per HOMEWORKLIB RULES.
Answer for question number 9.
3-Methylbutanal
Explanation
+
PBr3
+ Mg/Et2O
+
epoxide/H3O+
+
PCC/CH2Cl2
Answer for question 10.
Explanation
The reactant can form planar, stable, secondary cabocation, which allows the substitution of nucleophile in the SN1 manner. Hence the product formed will be 50% retention of configuration + 50% inversion of configuration.
+
CH3O-
+
Retention isomer Inversion isomer
Answer for question 11
Option. C. 
Explanation
+
H2O 
Keq is higher for the reaction that favours forward direction. In other words, where the product is favourably formed, there Keq will be high. This is because, [Product] is included in the numerator of Keq ratio.
Option C. has greater possibility to undergo hydration reaction, because of the -I effect of the 3 Cl- groups around C=O.
All other options are wrong.
Option. A. wrong, because it has only +I group substituents.
Option. B. wrong, because it has only one -I group substituent.
Option. D. wrong, because it has only two -I group substituents that too on the same side.
Answer for Question 12
Explanation
The reaction is a Diels-Alder reaction. This involves concerted mechanism. The "z" isomer is obtained as the product.
