Abstract:
From laboratory tests ensues a relatively small influence of ethanol on different functions which affect the ability to drive a motor vehicle. Under laboratory conditions ethanol protracts the simple reaction time surprisingly very little, at concentrations of 1 g/kg, 1.28 times (5). Despite this the relative risk of a fatal accident of the driver of a motor car at ethanol concentrations of 0.5-0.9 g/kg is nine times greater as compared with a sober driver (19). The problem behavior theory tries to explain this apparent contradiction (9).

Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
