Why can carbon combine with itself to make substances that have very different properties? (ex. graphite and diamond).
Because of carbon's 4 valence electrons it can form a variety of bonds with other carbons.
Because carbon is polar it can combine in a variety of ways.
Because carbon will either give or take 4 electrons so it can form various substances
Because carbon forms cations it combines in various ways.
The structure of graphite is most like which of the following?
A soccer ball
A cardboard box
A sheet of paper
A glass of water
What is it about coal that can make it a contributing factor to acid rain?
If the coal is burned at a high temperature, acid rain could form.
If the coal contains too much hydrogen, acid rain could occur.
If the coal isn't mined correctly, it could cause acid rain when burned.
If the coal contains too much nitrogen or sulfur, acid rain could occur.
What chemical reaction is this?
Photosynthesis
Cellular respiration
Enzyme production
Vitamin synthesis
When alkynes are treated with hot KMnO4, a triple bond is completely broken forming carboxylic acids and aldehydes depending upon the structure of alkyne.
TRUE
FALSE
In an alkyne hydrohalogenation reaction, addition of excess acid yields to a vinyl halide. *
TRUE
FALSE
Halogenation of alkynes can also proceeds through a bridged-ion intermediate, providing cis- products. *
TRUE
FALSE
Hydrohalogenation of alkynes also follows the Markovnikov's Rule which states that hydrogen adds to the carbon with the least number of hydrogen attached to it.
TRUE
FALSE
Lindlar's catalyst, prepared by deactivating (or poisoning) a conventional palladium catalyst by treating it with lead acetate and quinoline, permits alkynes to be converted to alkenes without further reduction to an alkane, hence forms a trans-alkene.
TRUE
FALSE
Ozonolysis of internal alkynes yields to a carboxylic acid.
TRUE
FALSE
Using a cold dilute potassium permanganate, alkynes are oxidized to form carboxylic acids or 1,2-diketones.
TRUE
FALSE
Water can be added across triple bonds in alkynes to yield aldehydes for internal alkynes and ketones for terminal alkynes.
TRUE
FALSE
Halogenation of an alkynes produces a final product of tetrahalide.
TRUE
FALSE
Which of the following is not a chemical properties of alkenes?
combustion
substitution
addition reaction
polymerisation
