Identify each type of bond:
zloy xaker [14]

Answer:

The type of bond between the Oxygen atom and the hydrogen is Covalent

this is because the 2 electrons are being shared by both hydrogen and oxygen

The type of bond this molecule makes as a whole is called a Hydrogen Bond

A hydrogen bond is formed because of the partial +ve and -ve charge in a molecule

The cause of the partial +ve and -ve charge is the comparatively high electronegativity of oxygen which makes the electron get attracted towards the oxygen atom while the hydrogens try to maintain the maximum distance from the lone pairs due to repulsion

Hope it helped

Which pair of atoms has the highest electronegativity difference?
finlep [7]
I'll go through them one by one
1) H-S
The electronegativity of Hydrgoen is 2.2, and sulphur is 2.58,
therefore the difference is 0.38 (2.58-2.2=0.38)
2) H-Cl
Hydrogen: 2.2, Chlorine: 3.16
therefore difference is 0.96
3) N-H
Nitrogen: 3.04, Hydrogen: 2.2
therefore difference is 0.84
4) C-H
Carbon: 2.55, hydrogen: 2.2
therefore difference is 0.35

so, the most apparent electronegativity is chlorine, but this could have been done without actually doing the maths. The trend of electronegativty increases across a period and increases up a period due to the strong affinity of the nucleus with bonding electrons. This does not include noble gases though, as they have no charge due to having complete valance shells. T<span>he most electronegative element is Fluorine (9), and the least electronegative element (besides noble gases) is Francium (87)</span>

Which atom(s) in the molecule CH3OCH3 will display tetrahedral electron-pair geometry? (Select all that apply)a. Ob. Cc. Hd. non
FrozenT [24]

Answer:

b. C

Explanation:

The geometry is how the bonds and the lone pairs of electrons are distributed around the atom, and the angles formed by them occurs to minimize the repulsive forces of the bonds and the lone pairs.

For example, the molecule of CO₂ is linear, because the central atom C has no lone pairs (the valence shell of it has 4 electrons, so it shares all of them to be stable), and do only two bonds. But the molecule of H₂O is angular, because the central atom O has two lone pairs (its valence shell has 6 electrons, so it only shares 2 electrons to be stable), and the repulsive forces are minimized with an angle of 104.45°.

To the geometry be tetrahedral, the atom must have 4 bonds, and none lone pairs, and it only happens at the two C in the molecule given. H only does one bond, and O does 2 bonds and has 2 lone pairs.
