The reagent, from the following, which converts benzoic acid to benzaldehyde in one step is
LiAlH4
KMnO4
MnO
NaBH4
The correct answer is (C) : MnO
Benzoic acid can be converted to benzaldehyde in presence of MnO.
Convert Ethanal to But-2-enal
Let \( A = \{-3, -2, -1, 0, 1, 2, 3\} \). A relation \( R \) is defined such that \( xRy \) if \( y = \max(x, 1) \). The number of elements required to make it reflexive is \( l \), the number of elements required to make it symmetric is \( m \), and the number of elements in the relation \( R \) is \( n \). Then the value of \( l + m + n \) is equal to:
For hydrogen-like species, which of the following graphs provides the most appropriate representation of \( E \) vs \( Z \) plot for a constant \( n \)?
[E : Energy of the stationary state, Z : atomic number, n = principal quantum number]
