The structural formula of cis-3-heptene and trans-3-heptene is to be drawn. The structural difference is to be determined also. Concept introduction: The structural formula of a compound represents the molecular structure along with the atom connectivity and bonding arrangement. An alkene is a molecule contains a double bond between two carbons atoms whereas alkynes are the hydrocarbons contain a triple bond. Alkenes general formula is C n H 2 n and alkynes general formula is C n H 2 n − 2 . Due to the presence of a double bond, the rotation about adjacent carbon-carbon atoms is highly restricted. Hence, alkenes can exist in two forms which have the similar molecular formula but a different type of arrangement of atoms around the double bond. This isomerism is a type of stereoisomerism which is known as geometric isomerism or cis-trans isomerism, for example, 1, 2-dichloroethane can show the geometrical isomerism,

Interpretation Introduction

Interpretation:

The structural formula of cis-3-heptene and trans-3-heptene is to be drawn. The structural difference is to be determined also.

Concept introduction:

The structural formula of a compound represents the molecular structure along with the atom connectivity and bonding arrangement. An alkene is a molecule contains a double bond between two carbons atoms whereas alkynes are the hydrocarbons contain a triple bond. Alkenes general formula is CnH2n and alkynes general formula is CnH2n−2. Due to the presence of a double bond, the rotation about adjacent carbon-carbon atoms is highly restricted. Hence, alkenes can exist in two forms which have the similar molecular formula but a different type of arrangement of atoms around the double bond. This isomerism is a type of stereoisomerism which is known as geometric isomerism or cis-trans isomerism, for example, 1, 2-dichloroethane can show the geometrical isomerism,

2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.
