Predict the electron pair geometry and the molecular structure of each of the following molecules or ions: (a) ClNO (N is the ce
S_A_V [24]

Answer:

See explanation

Explanation:

In ClNO , nitrogen is the central atom here. The central atom has a tetrahedral electron pair geometry and a lone pair on the nitrogen atom. Due to the lone pair, the electron pair geometry is now trigonal pyramidal.

The molecule CS2 has a linear molecular geometry. There are four electron groups around the central atom hence the electron pair geometry is tetrahedral but the molecular geometry results from the repulsion of the two double bonds.

The electron domain geometry for Cl2CO  is tetrahedral since there are four electron pairs around the central atom. However, the molecular geometry is trigonal planar due to the sp2 hybridization of the central carbon atom.

The electron domain geometry of Cl2SO  is tetrahedral due to the four electron pairs around the central atom. However, due to the lone pair on sulphur, the molecular geometry is  triagonal pyramidal.

In SO2F2, sulphur the central atom is surrounded by four electron pairs which are all bonding groups hence both the molecular geometry and the electron pair geometry is tetrahedral.

In XeO2F2, the central atom is Xe. There are five electron pairs around the Xe central atom four of which are bonding groups. The electron domain geometry and molecular geometry is trigonal bipyramidal.

For ClOF2 , the central atom Cl is surrounded by four electron pairs hence the electron pair geometry is tetrahedral but it is an AX3E(three bonding groups and one lone pair are present in the structure) specie hence it is trigonal pyramidal.

An alkene X undergoes ozonolysis and gives two compounds Y and Z of molecular formula CHO. Y and Z. are functional isomers of ea
AleksAgata [21]

The answers to the given questions are given below.

<h3>What is Ozonolysis ?</h3>

A reaction done with Ozone to determine the position of C-C double bond in unsaturated Hydrocarbons.

It is given in the question

An alkene X undergoes ozonolysis and gives two compounds Y and Z of molecular formula CHO

Y and Z. are functional isomers of each other

  • The two-steps chemical equation for the conversion of X into Y and Z.

\rm \\(CH_3)_2 -C= CH-CH_2-CH_3  + Zn - > CH_3 -CO-CH_3 +  CH0-CH_2-CH_3\\\\Y \;is \;CH_3 -CO-CH_3 \\\\and \;Z \;is \;CHO-CH_2-CH_3

  • Here X is 2 methyl pent-2 ene
  • On reaction with ozone , ozonide is formed

                         \rm Y \;is \;CH_3 -CO-CH_3 \\\\and \;Z \;is \;CHO-CH_2-CH_3

  • These are functional isomers as they have same molecular weight , but different functional groups.

  • When hydrogen gas in the presence of nickel catalyst is passed over  2 methyl pent-2 ene

  • A process called catalytic Hydrogenation will take place , and the alkene will get converted into alkane , 2-methyl pentane

  • The ozonolysis process is useful in the pharmaceutical industry

  • The unsaturation can be tested  by bromine water test
