Organic chemistry Flashcards
Longer chain hydrocarbons are more or less viscous?
More viscous, the concept can be studied from Crude oil fractional distillation
Longer chain hydrocarbons are more or less volatile?
Less volatile. For shorter chain hydrocarbons, they are more volatile, have low BP, and flow easily
T/F Larger molecules have the higher boiling points, are less viscous and are more flammable.
False, larger molecules have the higher boiling points, are more viscous and are less flammable.
Why longer hydrocarbon chains has higher boiling point?
Because they have more intermolecular forces compared to shorter alkane. Hence, more energy is needed to overcome them.
Reaction of Alkene with hydrogen. Addition or condensation?
Addition reaction
Alkene can react to which substances? List all possible ones.
Bromine, Halogens, Water, Hydrogen, H-X (hydrogen halides)
What should we use to test for unsaturated hydrocarbon?
Bromine can reacted with Alkene/ Alkyne. Decolorisation of bromine/ Halogenation
Rank 4 organic compounds that has high BP (in subsequent order)
Amide > Carboxylic acid > Alcohol > Amine
Rank the boiling point of all hydrocarbon from highest to lowest
Alkyne > Alkane > Alkene
Can alcohol reacts with NaHCO3
No, Alcohol can react only with Sodium
Which substance can react with Carboxylic acid
NaHCO3, NaOH, Na
Oxidation H increase or decrease
decrease, Reduction H increase
CnH2n+1OH Alcohol or Carboxylic acid
Alcohol
