(c) (i) Alcohol E can be converted to a liquid alkene in a reaction with concentrated phosphoric acid. Draw and label suitable apparatus to carry out this reaction and collect the alkene formed. (3) (ii) 15.0 g of alcohol E formed 9.84 g of the alkene cyclohexene, after purification. Calculate the percentage yield of the reaction.

The methyl group is attached to Carbon “2 and 3” ... 5.The = C= C = double bond in alkene is the functional group. A functional group is the reacting site of a molecule/compound. ... Addition polymers are named from the alkene/monomer making the polymer and adding the prefix “poly” before the name of monomer to form a polyalkene.

The Simmons-Smith reaction exhibits a strong directing effect and rate enhancement (with zinc when the alkene bears a heteroatom-containing functional group, and the methylene is delivered to the face of the alkene that is proximal to the heteroatom. Charette J. Organomet.

2-methyl, 2-hydroxybutanenitrile 2-hydroxybutanenitrile 2-hydroxypropanoic acid If one of the functional groups is an alcohol and the other is anything other than an amine or a haloalkane, the molecule is named by replacing the –an- part of the name with –en-, including a number if the position of the alkene has to be specified.

Functional group is an alkene, therefore suffix = - ene. The longest continuous chain is C5 therefore root = pent. The C=C is between C2 and C3, so the locant is 2-The substituent is a C1 alkyl group i.e. a . methyl. group . The methyl group locant is . 4- 4-methyl-2-pentene. or . 4-methylpent-2-ene

3. If there is more than one type of alkyl group in the molecule, list their names in alphabetical order. 4. If an alkyl group occurs more than once, use a . Latin prefix. to indicate the number present. The Latin prefixes are . di = 2, tri = 3, tetra = 4, penta = 5, and so on. - e.g. two methyl groups would be represented as dimethyl. 5.

a. The methyl group interacts with an extra hydrophilic binding region through van der Waals interactions. b. The methyl group increases the basicity of the ring nitrogen, making it a better hydrogen bond donor. c. The methyl group prevents the pyridine rings from being coplanar and prevents the molecule adopting the active conformation. *d.

For example, CH3-OH could be called methyl alcohol since the CH3 group is the methyl group. This method works as long as you have simple alcohols. When the alcohols become more complex and more branched, then IUPAC has come up with a set of rules that are used to name any alcohol regardless of its complexity.

This time there are two different alkyl groups attached - an ethyl group on the number 3 carbon atom and a methyl group on number 2. Filling in the hydrogen atoms gives: Note: Once again it doesn't matter whether the ethyl and methyl groups point up or down. You might also have chosen to start numbering from the right-hand end of the chain.
