Which hydrocarbon contains one double carbon carbon covalent bond? explain your answer.?

Question

It's about making polymers and its chemistry

Answer 1

Any alkene has one double carbon carbon double bond. Its general formula is Cn+2H2(n + 2)

The simplest is C2H4 ( H2C=CH2) known as ethylene

H . H
.| .. |
C=C
.| .. |
H . H

This polymerises to polyethylene (very ubiquitous indeed!!)

..... ... H . H ... H .. H
..... .... | ... | .... | .... | ...
..... —C—C—C—C— .....
..... .... | ... | .... | .... | ...
..... ... H . H ... H .. H

However there are many other carbon compounds with double bonds

Answer 2

There are lots of hydrocarbons that contain just one carbon-carbon double bond. They are called alkenes (old name olefins) and the two simplest are ethene (or ethylene) C2H4 and propene (or propylene) C3H6. After that, it becomes more complicated because of the large numbers of isomers possible. For example, there are four alkenes with the formula C4H8: but-1-ene, cis-but-2-ene, trans-but-2-ene and 2-methylpropene. By the time you get to C6H12, there are 16 isomeric alkenes, one of which (3-methylpent-1-ene) is optically active. The list is literally endless.

Since it's about making polymers, you should be aware that only terminal alkenes can undergo polymerisation readily. This means that the alkene has to have a structural formula ending in ===CH2 . So ethene polymerises to give polythene and propene polymerises to give polypropylene. But-1-ene and 2-methylpropene also polymerise fairly easily, but but-2-ene (whether cis- or trans-) will only polymerise with difficulty.

Answer 3

2 carbons and 1 double bond would give ethylene or ethene This also has 4 hydrogens, polymerisation of this gives polyethylene.

The hydrogens can also be replaced by other hydrobarbon groups to give different alkenes that give different polymers

Answer 4

isobutene (2-methylpropene). it truly is the nearest i can get. Please note alkenes react with water really in ACIDIC challenge. In propene, #a million carbon useful factors a H+ to furnish a secondary carbocation (fee on #2 carbon, extra strong), then water attacks the carbocation as a nucleophilie. The product is a secondary alcohol, 2-propanol. 2-methylpropene reacts with water in acidic challenge with a similar way. #a million carbon useful factors a H+ inspite of the indisputable fact that the fee relocate onto the tertiary carbon to furnish a strong tertiary carbocation, then suggested by nucleophilie attack. The product right here's 2-methyl-2-propanol. 2-methylpropene reacts extra straight away than propene, because the intermediate in 2-methylpropene reaction, it truly is a tertiary carbocation, is extra kinetically strong

Answer 5

This is an homologous group called ALKENES.

There are many alkenes.
The shortest is ETHENE (2 carbons in the chain)
The next is PROPENE (3 carbons in the chain, but only one C=C bond). CH3CH=CH2
The next is BUTENE . The double C=C can be in two different places in the chain . :-
BUT- 1-ENE (CH2=CHCH2CH3)
BUT -2-ENE (CH3CH=CHCH3)

NB: If there are 2 C=C bonds in the chain it is named a DIENE.
e.g. HEX-2,4-DIENE (CH3CH=CHCH=CHCH3)

NNB the number in the name indicates the carbon number in the chain where the C=C bond starts.

Answer 6

There are lots of them; the simplest is ethylene, C2H4. The resulting polymer, polyethylene, is ubiquitous.
