Alkanes And Alkenes Flashcards
(12 cards)
What is an alkane
Saturated hydrocarbons C-H bonds only
General formula of an alkane
Cn H2n+2
Alkanes are non polar because…
Carbon and hydrogen have similar
Electronegatvitieis
Shape and angle of alkane
Tetrahedral 109.5
Every alkane carbon has 4 what and what is it
Sigma bonds
Sigma bonds is a covalent bond that has a direct overlap of electron clouds of the bonding atoms
What forces do alkanes have
London because they are non polar
Boiling point of alkanes…
Increase as there are more London forces to break so more energy to overcome attraction
Branched molecules have…
Lower boiling points as they have fewer London forces
are alkanes soluble in water
No because hydrogen bonds in water are stronger than London forces.
Are alkanes reactive
No
