Gasohol is a godd motor fuel which reduces upto 30% carbon monoxide emission. Give the composition of Gasohol.

Empirical formula is the simplest formula of the compound which gives the atomic ratio of various elements present in one molecule of the compound. However the molecular formula of the compound gives the number of atoms of various elements present in one molecule of the compound. Molecular formula = (Empirical formula) xxn Which pair of species have same percentage composition of carbon?

What is the simplest formula of the compound which has the following percentage composition: Carbon 80%, hydrogen 20%.

What is the simplest formula of the compound which has the following percentage composition: carbon 80%, Hydrogen 20%, If the molecular mass is 30, calcualte its molecular formula.

An organic compound contains 69.77% carbon, 11.63% hydrogen and rest oxygen. The molecular mass of the compound is 86. It does not reduce Tollens’ reagent but forms an addition compound with sodium hydrogensulphite and give positive iodoform test. On vigorous oxidation it gives ethanoic and propanoic acid. Write the possible structure of the compound.

Monosaccharides and disaccharides in which aldehyde group is free reduce Tollen's reagent as well as Fehling solution and hence are known as reducing sugars. Carbohydrates react with excess of phcayl kydrazine to yield their crystalline derivatives called oxazones. In osazone formation only the first two carbon atoms are irrelved Osazone on hydrolysis gives same which are reduction with ZnCH_(3)COOH gives a ketose sugar The end product 'Z' in the following sequence of reactions. Glucose, underset(("excess"))overset(Ph. NH.NH_(2))rarr X underset(Delta)overset(H_(2)O//H^(+))rarr Y overset(Zn//AcOH)rarrZ

The work function for the following metals is given: Na: 2.75 eV, K: 2.30 eV, Mo: 4.17 eV, Ni: 5.15 ev . Which of these metals will not give photoelectric emission for a radiation of wavelength 3300 Å from a He-Cd laser placed 1 m away from the photocell? What happens if the laser is brought nearer and placed 50 cm away ?
