Answer:
C) sp2 and sp2
Explanation:
The hybridization depens on the ammount and type of bonds the atom analized has in the molecule.
For example:
- A C atom bonded to 4 H atoms has a sp3 hybridization.
- A C atom bonded to 2 H atoms and to 1 C with a double bond (like in ethene) has a sp2 hybridization
- A C bonded to 1 H and 1 C with a triple bond (like in ethyne) has a sp hybridization.
Analyzing the type and amount of unions of the nitrogen and the carbonyl you will be able to determine the hybridization.
In the imine, the N atom has a double bond to a C and a simple bond two other C, plus the lone pair of electrons (counts as a bond) so it will have a sp2 hybridization.
In the carbonyl, the C has two simple bonds to other C and a double bond to an oxygen atom. It will also have a sp2 hybridization
Answer:
<h2>D) 6</h2>
Explanation:
since, n = molar mass / empirical formula mass
Empirical formula mass = Total mass of atoms present in empirical formula
CHCl = 12+1+35.5
= 48.5
Given, Molar mass = 290.8 g.
So, n = 290.8/48.5
= 5.995 , that is approx 6.
So, Molecular formula = n × Empirical formula
= 6 × CHCl
= 
So, Number of C = 6
Explanation:
Oil molecules are non-polar, and they can't form hydrogen bonds. Dispersion forces are present in C12H26 (oil).
H20 (water) are polar, has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces.
The difference between them is that adhesion refers to the clinging of unlike molecules and cohesion refers to the clinging of like molecules.
In C12H26 (oil) the adhesive forces are stronger than the cohesive forces as a result, oil molecules tend to stick to the walls of the container.
In H2O (water) the cohesive forces is greater than the adhesive forces, as a result water molecules tend to stick together.
