The oxidation state of phosphorus in hypophosphoric acid is + _____
Let one focus of the hyperbola \( H : \dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1 \) be at \( (\sqrt{10}, 0) \) and the corresponding directrix be \( x = \dfrac{9}{\sqrt{10}} \). If \( e \) and \( l \) respectively are the eccentricity and the length of the latus rectum of \( H \), then \( 9 \left(e^2 + l \right) \) is equal to:
Classification of Alcohols Phenols and Ethers are as follows:
On the basis of dependence on the attachment of hydroxyl groups, alcohol can be classified into three different types:
On the basis of dependence on the different number of carbon atoms in a molecule that are bonded with the -OH group, alcohol can be classified into three different types:
On the basis of the attachment of the different number of hydroxyl groups, the phenols can be classified further into three types:
The Classification is dependant on the type of the alkyl or aryl groups attached to the oxygen atom in ether group, thus it can be classified into two types:
