The range for the above ungrouped data is 49 - 12 = 37. Normally it is desirable to divide the range into 6 to 10 classes. Consider the class 11 - 15. If a student scores 11 marks or 15 marks, he will be put in this class. For this class, 11 is the lower limit and 15 is the uppe..

When a haloalkane eliminates hydrogen halide in two different ways, then the preferred alkene is the one in which carbon atoms joined by the double bond are alkylated maximum i.e., contains largest number of alkyl groups. This rule is called 'Saytzeff's rule'. For example, The a..

Science is the way by which a person gets at the truth or at least as close to truth as possible. The basis of science is its orderly stepwise procedure - the scientific method. Scientific method employs various procedures such as, accurate observation, asking questions about the ..
