Is methanol soluble in CCl4?

Is methanol soluble in CCl4?

Propanol and butanol have limited water solubility, as do the higher alcohols. A more interesting question is whether methanol or ethanol dissolves in carbon tetrachloride. It is a fact that ethanol dissolves in petroleum ether, whereas methanol does not, and for the reasons given above.

Is CH3OH miscible?

Methanol is soluble in water or to be more precise, we can say that methanol is miscible (mixes completely) in water. This is possible mainly because of hydrogen bonding. Let us understand how it occurs. If we take Methanol (CH3OH), it has a strong hydrogen bonding force acting between its molecules.

Which one of the following would be most soluble in CCl4?

So, looking at your choice of compounds, the non-polar substance will be most soluble in CCl4. That would be the hydrocarbon. All of the other compounds are polar or ionic.

Why is cretinism not reversible?

The correction of iodine deficiency produces a dramatic reversal of the condition of cerebral hypothyroidism due to restoration of brain thyroid hormone levels. This is a different effect from brain damage during pregnancy, which is not reversible but completely preventable.

What is the symptoms of cretinism?

Signs of cretinism or congenital hypothyroidism in a newborn include:

  • lack of weight gain.
  • stunted growth.
  • fatigue, lethargy.
  • poor feeding.
  • thickened facial features.
  • abnormal bone growth.

How can cretinism be prevented?

About one billion people worldwide risk the consequences of iodine deficiency, all of which can be prevented by adequate maternal and infant iodine nutrition. Iodized salt is usually the preferred prophylactic vehicle, but iodized vegetable oil, iodized water, and iodine tablets are also occasionally used.

Can cretinism be cured?

Treatment. Congenital iodine deficiency has been almost completely eliminated in developed countries through iodine supplementation of food and by newborn screening utilizing a blood test for thyroid function. Treatment consists of lifelong administration of thyroxine (T4).
