A
Saturated
2
Q

A
CnH2n+2
3
Q
What is the general formula of a cycloalkane?
A

Can only have two hydrogens
4
Q
What is the shape that alkanes form?
A
Alkanes always form a tetrahedral shape around the carbon atom
5
Q
What is the size of the angle around each bond in an alkane?
A
109.5 degrees
6
Q
Why do alkanes have a specific shape with specific angles
A
The reason is because bonds repel each other equally. The bonds contain electrons so they want to be as far apart as possible
