Chapter 2 Flashcards
1
Q
Relationship between length of carbon chain and melting points
A
The longer the chain, the higher the boiling point
2
Q
Hydrocarbons
A
Consist only of carbon and hydrogen
3
Q
Valence electrons in SO4 ^2-
A
32
4
Q
To find the most polar covalent bond
A
It has the highest difference in electronegativities
5
Q
Bond angle in H2S is
A
Less than 109.5° because lone pairs force hydrogen atoms closer together

A
Boiling point of haloalkane is higher
8
Q

A
True
9
Q
