CH3CH2OH  →  H2C=CH2 + H2OSince water is removed from the same molecule, the reaction is known as intramolecular dehydration. Intramolecular dehydration of an alcohol requires a high temperature and the presence of an acid catalyst such as sulphuric acid.Ethylene produced from sugar-derived ethanol (primarily in Brazil) competes with ethylene produced from petrochemical feedstocks such as naphtha and ethane. At a lower temperature than that of intramolecular dehydration, intermolecular alcohol dehydration may occur producing a symmetrical ether. This is a condensation reaction. In the following example, diethyl ether is produced from ethanol:

2 CH3CH2OH  → CH3CH2OCH2CH3 + H2O

Combustion
Complete combustion of ethanol forms carbon dioxide and water:

C2H5OH (l) + 3 O2 (g) → 2 CO2 (g) + 3 H2O (l); −ΔHc = 1371 kJ/mol = 29.8 kJ/g = 327 kcal/mol = 7.1 kcal/gC2H5OH (l) + 3 O2 (g) → 2 CO2 (g) + 3 H2O (g); −ΔHc = 1236 kJ/mol = 26.8 kJ/g = 295.4 kcal/mol = 6.41 kcal/gSpecific heat = 2.44 kJ/(kg·K)

Acid-base chemistry
Ethanol is a neutral molecule and the pH of a solution of ethanol in water is nearly 7.00. Ethanol can be quantitatively converted to its conjugate base, the ethoxide ion (CH3CH2O−), by reaction with an alkali metal such as sodium:
2 CH3CH2OH + 2 Na → 2 CH3CH2ONa + H2or a very strong base such as sodium hydride:

CH3CH2OH + NaH → CH3CH2ONa + H2The acidities of water and ethanol are nearly the same, as indicated by their pKa of 15.7 and 16 respectively.
A child with a spastic CP diagnosis will likely be referred to screening for other conditions associated with spastic cerebral palsy such as epilepsy (seizure disorder), intellectual disability, and visual impairment. Types
Scientific classifications
The types of spastic cerebral palsy are generally distinguished by the primary areas of the body that are affected. Spastic hemiplegia Hemiplegia is a type of cerebral palsy affecting one vertical half of the body (such as one arm and one leg). The affected side of the body is opposite the affected area of the brain in hemiplegia. For example, if the right side of the brain is damaged, the person will have weakness or paralysis on the left side of the body. People with hemiplegia typically favor an arm or hand and may keep the weaker hand in a fist. Typically, people that have spastic hemiplegia are the most ambulatory of all the forms, although they generally have dynamic equinus (a limping instability) on the affected side and are primarily prescribed ankle-foot orthoses to prevent said equinus. Spastic diplegia describes spastic CP in which muscle tightness predominantly occurs in the legs. The arms may be somewhat affected or not affected at all. Spastic monoplegia is one single limb being affected. Spastic triplegia is three limbs being affected. Spastic quadriplegia is all four limbs more or less equally affected. People with spastic quadriplegia are rarely able to ambulate without assistance and may not stand at all.
