Your chemistry professor draws a number of molecules on the board: (1) CH4 ; (2) H2C=CH2 ; (3) H2C=C=CH2 ; and (4) H2C=C=C=CH2. You muse about all the molecules that chemists draw on a two-dimensional board and wonder which ones are actually planar, existing basically as they appear on the board, and which ones are not plane but rather three-dimensional. Answer the following questions. What is the geometry and hybridization of the carbon in CH4? What is the geometry and hybridization of each central carbon atom in the remaining molecules? Draw each molecule showing the bonds and identify each bond in all the molecules as s or p. What are the specific orbital overlaps (i.e., sp3-sp3) that are in each of the molecules? What are the bond angles for each central atom in each molecule? Which molecules are planar and which are non-planar?

Predict the longest continuous chain of carbon atoms:

Chemistry, Chapter 24, Problem 24.26QP , additional homework tip 14

The longest continuous carbon chain of carbon atoms contains five carbons and the parent name is PENT-2-YNE. The Suffix ‘2-yne’ represents the structure contains one triple bond at C-2.

Predict substituents and its location:

Chemistry, Chapter 24, Problem 24.26QP , additional homework tip 15

No substituents present and no prefix can be written. Hence, the name is,

IUPAC name: Pent-2-yne.

Expert Solution

Interpretation Introduction

Interpretation:

The given structure has to be named.

Concept introduction:

IUPAC Nomenclature for alkene:

The longest continuous chain of carbon atoms is identified.
The substituent groups attached to the parent chain is identified. A substituent group contains group of atoms attached to the carbon atom of the chain.
While numbering the longest chain, the double bond should get least possible number.
Write the name of the compound; the parent name written as last part of the name by replacing ‘ane’ to ‘ene’. The name of the substituents is written as prefix and a hypen separates the number that the substituents attached with carbon. More than one substituent should be written in alphabetical order.

Geometric isomers of Alkenes:

Cis-isomer: When two particular atoms (group of atoms) are adjacent to each other, the alkene is known as cis-isomer.

Trans-isomer: When two particular atoms (group of atoms) are across from each other, the alkene is known as cis-isomer.

At each Carbon of 3 one phenyl group is present. Hence, the structure containing one substituent, then prefix ‘3-phenyl’ is added before the parent name. Hyphen separates the number that the substituent attached with carbon.

IUPAC name: 3-phenylpent-1-ene.
