Alkanes

Question 1

what are alkanes

Answer 1

saturated hydrocarbons

Question 2

what are alkanes general formula

Answer 2

CnH2n+2

Question 3

what is the general formula of a cycloalkane

Answer 3

CnH2n

Question 4

what shape are alkanes and what is their bond angle

Answer 4

tetrahedral
109.5

Question 5

why do alkanes boiling points increase as they get bigger

Answer 5

more surface contact so more induced dipole-dipole forces therefore more energy to break bonds

Question 6

why are alkanes good fuels

Answer 6

they burn in oxygen completely

Question 7

when alkanes burn in a limited supply of oxygen what is produced

Answer 7

carbon monoxide and carbon (soot)

Question 8

what is heterolytic bond fission

Answer 8

when a bond breaks but the two electrons are distributed unequally to form two different ions

Question 9

what is homolytic bond fission

Answer 9

when a bond breaks an the pair of electrons in the bond being shared equally to form two uncharged radicals

Question 10

why do alkanes form tetrahedral molecules

Answer 10

the bonds repel equally n
