Concept explainers
Interpretation:
Structural formula of (10E,12Z)-10,12-hexadecadien-1-ol has to be drawn.
Concept Introduction:
- • Name the main chain: Find the longest carbon chain and name the chain according to the number of carbon atoms it contains; is also the root name.
- • Number the carbon atoms in the main chain: The carbons are numbered, in which the substituents must get lowest possible numbers.
- • Identify the substituents, and number each: The number at where substituents are present has to be noted. The substituents written as prefix.
- • Write the names as a single word: Use the hyphen to separate the numbers from the different prefix; commas to separate numbers. If two or more different substituents are present, arrange them in alphabetical order. If two or more identical substituents are present, use prefixes di-, tri-, tetra-, but this particular prefix should not be used for alphabetizing purpose.
Alkene:
The systematic name of alkenes are written by replacing “ane” of
E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the bond.
Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the bond.

- The reaction of 1-bromohexane with potassium cyanide will produce a(n) __________. aldehyde nitrile ketone alcohol aminearrow_forwardAmines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.arrow_forwardWhen 3-methyl-1-butene reacts with HBr, two alkyl halides are formed: 2-bromo-3-methylbutane and 2-bromo-2-methylbutane.
