Draw structural formulas for each of the following molecules...

Draw structural formulas for each of the following molecules, then predict the hybridization and molecular geometry about each "central" atom. (Remember the octet rule when assembling the chemical formulas into structural formulas.) There is not one central atom; each central atom that has more than one atom bonded to it can be treated as a "central" atom. A) C3H6O B) C2H5OH C) C4H8 D) C6H11CO2H E) NH2CH2CO2H

00:01 In this question we are assigned with the task to give the molecular geometry and hybridization around each central atom.

00:13 First compound given is 3 -h -6 -o and this compound has 3 carbon and its structural formula is given here.

00:28 This is the structural formula for the given compound.

00:31 Since these two carbons are doubly connected, they are sp2 -h -5 .5.

00:36 And this carbonous sp hybridized sorry sp3 hybridized and this oxygen is also sp3 hybridized the molecular geometry around this carbon is tetrahedral and molecule geometry around oxygen is also tetrahedral and molecular geometry around the sp2 hybridized carbonous triangle planar now let us move on to the second compound and the molecular formula is c2 h5 oh h structural formula for this compound is this is the structural formula.

01:13 Both the carbons are sp3 hybridized, hence they have tetrahedral molecular geometry and this oxygen is also sp3 hybridized but due to the presence of two lone pairs of electrons, this oxygen is present in distorted tetrahedral geometry and it is also the case in the above given compound that is c3 had 6o.

01:40 I have missed to explain this point.

01:42 Now let us move on to the third compound.

01:46 It is c4 hachate.

01:48 This is the structural formula for the given compound.

01:52 These two carbons are doubly connected, hence they are sp2 hybridized and molecular geometry is trigonal planar.

02:00 And this carbon has just single bonds around it, hence it is sp3 hybridize...
