Answer:

The simulated 1H NMR spectrum for ethyl acetate is shown in the drawing attached.

Explanation:

To construct this NMR it is necessary to identify the essential components that can produce resonance peaks.

Two main groups can be identified, the acetyl group containing a sub-component (CH3) capable of producing a resonance peak, and the ethyl group containing two components (CH2 and CH3) each of which can produce on its own its own resonance peak.

What mass of hcl gas must be added to 1.00 l of a buffer solution that contains [aceticacid]=2.0m and [acetate]=1.0m in order to
Paraphin [41]
PH of acidic buffer = pKa + log [CH₃COONa - HCl] / [CH₃COOH + HCl]
pKa of CH₃COOH = 4.74
Concentration of acetic acid in buffer = 2.0 M
Concentration of sodium acetate = 1.0 M
Concentration of HCl must add = x
pH = 4.74 + log (1-x) / (2+x) = 4.11
x = concentration of HCl must be added = 0.43 M
number of moles of HCl = M * V = 0.43 * 1 = 0.43 mol
mass of HCl must be added = 0.43 * 36.5 = 15.7 g

Select the single best answer. Explain the observed trend in the melting points for four isomers of molecular formula C7H16. mp
damaskus [11]

Answer:

The ability of the molecule to pack more tightly increases the melting point.

Explanation:

In hydrocarbons of same molecular formula, melting point is determined by:

  • weak intermolecular forces
  • Molecular symmetry

Higher the intermolecular forces and molecular symmetry, higher will be the melting point.

Intermolecular forces in hydrocarbons decreases with branching. Moreover, branching interfere the tight packing of the molecule in the crystal. Therefore, branched hydrocarbons tend to have lower melting point.

However, in highly branched hydrocarbons molecular symmetry increases which results in tight packing of the molecule in the crystal.

So, highly tight packed molecules tend to have high melting point.

As (CH3)2CHC(CH3)3 is highly branched and has high molecular symmetry, therefore, its melting point is highest among given.

So, among the given, option c is correct.
