London force:

London force is an intermolecular force which occurs between an atoms or molecules which are polar or non-polar and another atom or molecule which are polar or non-polar. Hence it occurs between all molecules or atoms. The London dispersion force is a temporary attractive force which cause due to temporary dipoles of electrons in two adjacent atoms. This is also known as induced dipole-induced dipole attraction. It is a weakest Intermolecular force.

therefore the correct answer is D.

Identify the structure of a minor product formed from the radical chlorination of propane, which has molecular formula C3H6Cl2 a

Novosadov [1.4K]

Answer:

As we are not provided with ¹H-NMR spectrum therefore we can not conclude a single result for the minor chlorination of propane with Molecular formula C₃H₆Cl₂.

Hence, we will draw all the possible isomers with molecular formula C₃H₆Cl₂ and predict the ¹H-NMR spectrum for each of them separately.

Below is the structures of possible minor products and the NMR spectrum respectively.

Possible Product A:

If the minor product formed is 2,2-Dichloropropane then it will give only one singlet peak in NMR spectrum.

Possible Product B:

If the minor product is 1,1-Dichloropropane then it will exhibit two triplets and one multiplet as shown in figure.

Possible Product C:

If the minor product is 1,2-Dichloropropane then it will give four peaks in NMR. The extra peak is formed due to two enantiomers about the chiral carbon.

Possible Product D:

If the minor product is 1,3-Dichloropropane then it will exhibit one triplet and one quintet signal as shown in figure.

This is the chemical formula for nickel tetracarbonyl (a powerfully poisonous liquid used in nickel refining):nico4a chemical en

lesya [120]

Answer : There are 7.0 moles of oxygen in the formula.

Explanation :

The chemical formula of nickel tetracarbonyl is Ni(CO)₄.

We can see that there are 4 carbon atoms and 4 oxygen atoms which together form 4 carbonyl (CO) groups.

Therefore the mole ratio of C to O is 1 : 1.

Let us use this as a conversion factor to find moles of oxygen.

We have 7.0 moles of carbon in the formula.

The moles of O can be calculated as,

$7 mol C \times \frac{1 mol O}{1 mol C} = 7.0 mol O$

There are 7.0 moles of oxygen in the formula.

Addition reactions of alkenes are characterized by _________. A) formation of a bond B) addition of two groups across a double b

mr_godi [17]

Answer:

B. ADDITION OF TWO GROUPS ACROSS A DOUBLE BOND

Explanation:

Addition reaction of alkenes involves the conversion of the double bond in alkenes Inyo single bonds by the addition of two groups of atoms or radicals.

During this addition reaction, two substances, an unsaturated compound(e.g. ethane) and an attacking reagent (hydrogen, halogens, hydrogen halides, chlorine and bromine water) combines to form a single new compound without forming any other products. So a saturated product or one in which is an increase in degree of saturation is formed.
