Name the groups whose elements prefer to form molecular hydrides.

Explanation

To answer the question about which groups of elements prefer to form molecular hydrides, we can follow these steps:

### Step 1: Understand Molecular Hydrides
Molecular hydrides are compounds formed between hydrogen and other elements, where hydrogen is covalently bonded to the other element. These compounds typically involve nonmetals or metalloids.

### Step 2: Identify Relevant Groups in the Periodic Table
The groups in the periodic table that are known to form molecular hydrides include:
- **Group 14 (Carbon Group)**: Elements like carbon (C) and silicon (Si) form hydrides such as methane (CH₄) and silane (SiH₄).
