Chapter 1 - Introduction

Question 1

Define a nucleophile and an electrophile

Answer 1

Nucleophile = nucleus loving, negatively charged
Electrophile = electron loving, positively charged
*the stronger the nucleophile, the stronger the base

Question 2

What is the difference between a (non-zero) dipole moment and a zero dipole moment

Answer 2

Zero dipole moment = symmetrical
Dipole (non zero dipole moment) = nonsymmetrical
Dipole = Difference
Dipole = polarised

Question 3

What is a sigma bond?
How many sigma bonds in
CH2=CH-CH2-CH=CH2

Answer 3

Sigma = single
there are 3 single bond C + 1 (rule) = 4 (rule is =1 for alkenes and +2 for alkynes)
Plus the 8H also so 12 sigma bonds

Question 4

What is a pi bond?

Answer 4

C-C bonds that are double or triple bonded.
