Question

can someone please help me answer questions #10, #11, & #12 please with clear explanation and neat handwriting!! will give good rating:) make sure you are correct thank you so much!

Question 10 Consider the following molecules (1, II and III). CH3 CH2CH3 C CH2OH сн. C.CH C-CH2OH OH OHT Select all the chiral molecules. O All of them are chiral. None of them are chiral. (II) and (III) (I) and (11) O (l) and (III)

Answer 1

Look for carbons with four different groups attached to identify potential chiral centers. Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral.

In compound (I) all four hands attached to carbon are different, therefore it is chiral carbon

In compound (II) also all four hands attached to carbon are different, therefore it is chiral carbon

In compound (III) two hands attached to carbon are same, therefore it is achiral carbon

Therefore correct answer is (I) and (II)

NOTE- you please upload other questions separately.

Questions that are posted on the boards all differ in length and complexity. They often include subparts- like a, b, c, d, i, ii. In order to make the best use of your valuable answering time, please follow the following protocol for questions with many subparts:

• More than 1 question: answer the first question
  • Unless a student explicitly mentions a question to answer- for instance, “answer the third question”. In this case, the question requested should be the one answered.

Your one thumbs up will help me lot. Thanks!
