Molecular formula for 2-hexene

Answer 1

3-Hexene: CH3CH2CH=CHCH2CH3 to name alkenes: -identify the parent chain (how many carbon atoms are in formula=prefix) there are 6 carbon atoms so the prefix is "hex" (prefixes are online) then add the end of the word alkene --> "ene" to that prefix. -Label where the double bond is located (on which carbon atom that has the lowest numeral positioning, numbering from either side) 3-hexene, you know that the double bond is at the 3rd carbon atom -the hydrogen atoms are determined by the number of covalent bonds the carbon atom can have (4) the first "C" has 3 hydrogen atoms bonded to it because it's only using one bond the second "C" has only 2 because its bonding in front and behind it (using 2) the third "C" has 1, the double bond takes 2 and the bond behind uses 1 (3) hope this helps -Autumn

Answer 2

2-methylcyclohexene does not exist. It is actually 1-methylcyclohexene. 2-methylcyclohexene indicates that the methyl group is bonded to one side of a carbon-carbon double bond in a six-carbon ring. The double bond tells you where to start numbering. Therefore, the methyl group would actually be on carbon #1. The only way to have 2-methylcyclohexene is if there is another group attached to the ring that changes the numbering.

c7H12 is the formula

Edit (9/23/14): The Methyl group is numbered 2 to indicate that the double bond present in the molecule, indicated by the "-ene" suffix, is on the first carbon. In the naming system the double bond is given numerical priority over the substituents. This means that 2-methylcyclohexene is a 6C ring with a double bond present between the first and second Carbons, and a methyl group substituent (CH3) on the second Carbon. The part about C7H12 is correct though.

Answer 3

what is the molecular formula of 3-methyl-2-hexanol

Answer 4

The organic compound 2-hexene that is commonly used as a comonomer in production of polyethylene. The molecular formula for 2-hexene is C6H12.

Answer 5

C6h12

ch3ch=ch(ch2)2ch3

ch3ch=chch2ch2ch3

Answer 6

Ch3 ch2 c=c ch(ch3)2
