(a)
Interpretation:
The formula of each hydride given in the picture has to be written and the compounds are either ionic, covalent or interstitial should be identified.
Concept Introduction:
The compound containing hydrogen and just one other element is called as binary hydride. Type of hydride formed depends upon the element present in the group. Types of binary compounds are, ionic hydride, metallic hydride and covalent hydride.
Ionic hydride: Ionic hydrides are formed by alkali metals and heavier alkaline earth metals. They contain cations and
Covalent hydride: Covalent hydrides are formed by non-metals. These compound contains hydrogen which is bonded to another element by covalent bond. Most of the covalent hydrides have relatively weak intermolecular force of attraction, so they are gas or volatile liquid at normal temperature.
Metallic hydride: Metallic hydrides are formed by

- Beer’s Law is A = εbc, where A is absorbance, ε is the molar absorptivity (which is specific to the compound and wavelength in the measurement), and c is concentration. The absorbance of a 2.31 × 10-5 M solution of a compound is 0.822 at a wavelength of 266 nm in a 1.00-cm cell.
