If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, how many isomers would result?
Mandarinka [93]

One isomer is formed

1,1- Dichloroethane is the isomer.

If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, it would result in one isomer.

  • In contrast to 1,2-dichloroethane, which has two chlorine atoms connected to distinct carbon atoms, 1,1-dichloroethane has two chlorine atoms bound to the same carbon atom.
  • Isomers are each of two or more compounds having the same formula but various atom arrangements in the molecule and unique characteristics.

<h3>What three types of isomers are there?</h3>
  • Chain isomers
  • Functional group isomers
  • Positional isomers

These are the three different categories of structural isomers.

<h3>How is an isomer recognized?</h3>
  • Their bonding patterns and the way they occupy three-dimensional space can be used to distinguish them.
  • Determine the bonding patterns of structural (constitutional) isomers.
  • Although the atoms in the compounds are the same, their connections create various functional groups.

<h3>What makes isomers significant?</h3>
  • Because two isomers might have the same chemical formula but different chemical structures, they are significant.
  • The molecule's properties are influenced by its structure.

If the atomic weight of nitrogen is 14.01, what is the mass of the nitrogen atoms in one mole of cadmium nitrate, Cd(NOÀ)
Nadya [2.5K]
The answer is 28.02.

The chemical formula for cadmium nitrate is Cd(NO₃)₂.

There are in total 2 nitrogen atoms in Cd(NO₃)₂. If <span>the atomic weight of nitrogen is 14.01</span>, the mass <span>of two nitrogen atoms in one mole of cadmium nitrate is 28.02:
2 </span>· 14.01 = 28.02
