According to picture below, p atomic orbitals overlap are responsible for the π bond between carbon and oxygen.
Both carbon and oxygen have sp2 hybridization in this carbonyl group. Carbon has three sigma bonds with sp2 orbitals and oxygen has one sigma bond with sp2 and two free electron pairs with sp2 orbitals. Pi bonds are formed between two p orbitals.

What is the difference between polar and non-polar

ExtremeBDS [4]

Answer:

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Answer:

Down below <3

Explanation:

1. 1 $N_{2}$ + 3 $H_{2}$ ---> 2 $NH_{3}$

2. 2 $KClO_{3}$ ---> 2 KCl + 3 $O_{2}$

3. 1 $Na_{3}PO_{4}$ + 3 HCl ---> _ 3_ NaCl + 1 $H_{3}PO_{4}$

4. 1 $C_{2}H_{6}O$ + 3 $O_{2}$ ---> 2 $CO_{2}$ + 3 $H_{2}O$

What is penetration? How is it related to shielding? Use the penetration effect to explain the difference in relative orbital en

Whitepunk [10]

Answer: penetration is the ability of an electron in a given orbital to approach the nucleus closely. Shielding refers to the fact that core electrons reduce the degree of nuclear attraction felt by the orbital electrons. Shielding is the opposite of penetration. The most penetrating orbital is the least screening orbital. The order of increasing shielding effect/decreasing penetration is s<p<d<f.

Explanation:

The order of penetrating power is 1s>2s>2p>3s>3p>4s>3d>4p>5s>4d>5p>6s>4f....

Since the 3p orbital is more penetrating than the 3d orbital, it will lie nearer to the nucleus and thus possess lower energy.

How many daltons is in an ion with 15 protons, 16 neutrons and 17 electrons?

Vera_Pavlovna [14]

31
A dalton is the same as an atomic mass unit. And an atomic mass unit is approximately the mass of a nucleon (proton or neutron) such that the mass is 1 g/mol. So in this problem you have 15 protons and 16 neutrons, so the number of daltons is 15 + 16 = 31.
