Answer 1

QUESTION 26

The easiest definition of a chiral carbon is a carbon with: four different substitutions

QUESTION 27

What is the molecular geometry of the nitogen in the primary amine (-NH2) functional group - trigonal pyramidal

QUESTION 28

How many carbons atoms are present in hept-3-yne

The root word hept represents seven carbon atoms so the Number of C atoms are 7.

QUESTION 29

How many carbons atoms are present in 2-methyl butane?

The root word but represents four carbon atoms & the substituent methyl represents one C atom thereby totally 4 +1 = 5 carbon atoms.

QUESTION 30

How many carbons atoms are present in a heptane chain?

The root word hept represents seven carbon atoms so the Number of C atoms are 7.

In Question numbers 31 & 32 , atoms are not displayed
