Lecture 2 Flashcards
1
Q
structural formula
A
shows atom connectivity
lines = chemical bonds
2
Q
molecular formula
A
shows the atoms
3
Q
element formula
A
simplest ratio
4
Q
skeletal formula
A
check notes
5
Q
single bond
A
2 electrons shared
can rotate
6
Q
double bond
A
4 electrons shared
can’t rotate
flat, planar
7
Q
triple bond
A
6 electrons shared
can’t rotate
8
Q
trend in bonds
A
as size decreases, strength increases
single -> double -> triple
9
Q
isomers
A
same molecular formula, different connectivity
very different reactivity and properties
