Which has higher boiling point ch3och3 or CH3CH2OH?
Which has higher boiling point ch3och3 or CH3CH2OH?
(c) Both CH3OH and CH3CH2OH can H-bond but CH3CH2OH has more CH bonds for greater dispersion force interactions. Therefore, CH3CH2OH has the higher boiling point.
Does ch3 have a high melting point?
Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules….Molecular Polarity.
| Compound | pentane |
|---|---|
| Formula | CH3(CH2)3CH3 |
| Boiling Point | 36ºC |
| Melting Point | –130ºC |
Which molecule has higher melting point?
Ice (solid H 2 O) is a molecular compound whose molecules are held together by hydrogen bonds. Though hydrogen bonds are the strongest of the intermolecular forces, the strength of hydrogen bonds is much less than that of ionic bonds. The melting point of ice is 0°C….Melting Point.
| Material | Melting Point (°C) |
|---|---|
| pure gold | 1063 |
| iron | 1538 |
What is the melting point of ch3?
The last compound, an isomer of octane, is nearly spherical and has an exceptionally high melting point (only 6º below the boiling point)….Boiling Points.
| Compound | tetramethylbutane |
|---|---|
| Formula | (CH3)3C-C(CH3)3 |
| Boiling Point | 106ºC |
| Melting Point | +100ºC |
Does CH3 3N or CH3 2nh have a higher boiling point?
Among (CH3)3N and CH3NH2 , amine with methyl groups attached has the higher boiling point.
Which has a higher melting point CH3OH or CH3CH2OH?
CH3CH2OH has more dispersion forces than CH3OH, so it has the highest boiling point. Melting points of the hydrogen halides increase in the order HCl < HBr < HF < HI.
Which amides are soluble in water?
10.6: Physical Properties of Amides
| Condensed Structural Formula | Name | Solubility in Water |
|---|---|---|
| CH3CONH2 | acetamide | soluble |
| CH3CH2CONH2 | propionamide | soluble |
| CH3CH2CH2CONH2 | butyramide | soluble |
| C6H5CONH2 | benzamide | slightly soluble |
What is carbons melting point?
6,422°F (3,550°C)
Carbon/Melting point
Which ionic compound has the highest melting point?
The greater the charge on the ions, the stronger the forces holding them together. Sodium chloride is made from Na + ions and Cl – ions and has a melting point of 801°C. Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.
Which of the following has the highest melting point but least solubility in a given solvent?
Thus,NaCI with the maximum lattice enthalpy has the highest melting point but the lowest solubility in water.
Is benzaldehyde soluble in water?
Water
Benzaldehyde/Soluble in
Why does CH3 3N have a low boiling point?
The amine ch3ch2ch2nh2 has the boiling boiling point due to the fact that it has the longest carbon chain. (CH3)3N has the shortest carbon chain and thus has the lowest boiling point.
What is the best solute in water?
Water is a polar molecule that exhibits hydrogen bonding, so the best solute is another polar compound. For this problem, we need to determine the polarity of each molecule. Which compound is the most soluble in water?
Which compound has the highest boiling point?
Which compound has the highest boiling point? Lobelia (structure shown) is a natural alkaloid found in a number of plants including “Indian tobacco” (Lobelia inflata) and “Devil’s tobacco” (Lobelia tupa). Lobelia has been used as a smoking cessation aid.
Is 3-chloro-2-hydroxybutanoic acid an acid or a base?
The compound 3-chloro-2-hydroxybutanoic acid is an a-hydroxy acid. True or false When a carboxylic acid is dissolved in water, an acid-base equilibrium occurs: the carboxylic acid donates a proton to H20, forming its conjugate base, a carboxylate anion, and water gains a proton, forming its conjugate acid, H30+. True or false
What happens when a carboxylic acid is dissolved in water?
True or false When a carboxylic acid is dissolved in water, an acid-base equilibrium occurs: the carboxylic acid donates a proton to H20, forming its conjugate base, a carboxylate anion, and water gains a proton, forming its conjugate acid, H30+. True or false When trimethylamine is heated up with propanoic acid, an amide is formed.
