When heated up with propanoyl chloride, which of the following nitrogen-cont compounds would NOT result in an amide? A. triethyl

mario62 [17]

Answer:

Option A is correct. A tertiary amine will not form an amide with acyl chlorides they can only transform acyl chlorides into ketenes.

Explanation:

(a). Reaction of acyl chloride with aniline: Aniline is the simplest primary amine. The -NH2 group is attached directly to the benzene ring. The equation of reaction is given below;

CH3COCl + 2C6H5NH2----------> CH3CONHC6H5 +C6H5NH3Cl.

The products of the reaction are The products are N-phenylethanamide,C6H5NH2 and phenylammonium chloride, C6H5NHCl.

(b). Reaction of acyl chloride with primary and secondary amine:

The -NH2 is attached to an alkyl group for the primary and secondary amine. Typical reaction equation for a primary amine with acyl chloride is given below;

CH3COCl + CH3NH2------------------> CH3CONHCH3 + HCl.

The HCl will further react with NH3 to produce The salt is called methylammonium chloride.

(c). Reaction of acyl chloride with amine: the equation of reaction is given below;

CH3COCl + NH3 --------------> CH3CONH2 + HCl.

The hydrogen chloride produced reacts with excess ammonia to form ammonium chloride;

NH3 + HCl ---------------> NH4Cl.

Solve,55.1 grams of tin at 90.6°C is dropped into a calorimeter with 75.4 grams of water at 21.0°C.The temperature of both the m

Lostsunrise [7]

Answer:

$C_{tin}=0.560\frac{J}{g\°C}$

Explanation:

Hello there!

In this case, for this calorimetry problem, we can notice that the heat evolved by the hot tin is gained by the cold water as the calorimeter is perfectly isolated, so we can write:

$-Q_{tin}=Q_{water}$

Thus, by defining the heats in terms of mass, specific heat and temperatures, we get:

$-m_{tin}C_{tin}(T_F-T_{tin})=m_{water}C_{water}(T_F-T_{water})$

Now, since we are asked for the specific heat of tin, we solve for it as shown below:

$C_{tin}=\frac{m_{water}C_{water}(T_F-T_{water})}{-m_{tin}(T_F-T_{tin})}$

Thus, when we plug in, we obtain:

$C_{tin}=\frac{75.4g*4.184\frac{J}{g\°C} (27.2\°C-21\°C)}{-55.1g(27.2\°C-90.6\°C)}\\\\C_{tin}=0.560\frac{J}{g\°C}$

Regards!

Is the following compound an alcohol, aldehyde, or organic acid? C-C=0

Pavlova-9 [17]

Answer:

Explain both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigon planar; the carbon atom exhibits sp2 hybridization. Two of the sp2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule. The remaining sp2 hybrid orbital forms a σ bond to the oxygen atom. The hybridized p orbital on the carbon atom in the carbonyl group overlaps a p orbital on the oxygen atom to form the π bond in the double bond.ation .
