Sodium borodeuteride is a commercially available reducing reagent that can convert aldehydes and ketones to the corresponding al
kupik [55]

Here we have to draw the mechanism of the reduction reaction between benzaldehyde and sodium borodeuteride to form the corresponding alcohol.

The reducing agent sodium borodeuteride can reduce the aldehydes to its corresponding alcohol. The reaction mechanism is shown in the attached image.

The reaction mechanism can be explained as-

The sodium borodeuteride is highly ionic in nature thus it remains as Na⁺ and BD₄⁻ The deuterium atom of BD₄⁻ attack the carbonyl carbon atom and substitute one of its deuterium as shown in the figure.

One molecule of sodium borodeuteride can reduce four molecules of benzaldehyde. The polar solvent like alcohol donates the proton as shown in the mechanism.

The converted alcohol contains the deuterium atom at the -C center. Thus benzaldehyde is converted to deuteroted benzyl alcohol.

Sample of gas occupies 10.0 L at 50 ˚C. Assuming that the pressure is constant what volume will
scZoUnD [109]

Answer:

<em>20 Liters</em>

Explanation:

If the pressure is supposed to be constant, one of Charles - Gay Lussac's laws can be used to solve the exercise. His statement says that "the volume of the gas is directly proportional to its temperature at constant pressure", mathematically it would be:

\frac{V1}{T1} = \frac{V2}{T2}

Considering T₁ = 50 ° C; V₁ = 10.0 L; and T₂ = 100 ° C, we can calculate the volume V₂ Clearing it from the equation and replacing the values to perform the calculation:

V2= (V1 x T2) / T1  = (10.0 L x  100°C)  / 50 °C = 20 L

Therefore, <em>the gas at 100 ° C will occupy a volume of 20.0 L</em>.

How many moles of Boron (B) are in 5.03 x 1024 B atoms?
goldfiish [28.3K]

Hey there!:

Number of moles =   ( number of atoms / 6.023*10²³ atoms )

given number of atoms = 5.03*10²⁴

Therefore:

Number of moles B = 5.03*10²⁴ / 6.023*10²³

Number of moles B = 8.35 moles

Hope that helps!
