State True or false
a chiral carbon consists of 4 different groups Attached.

Explanation

To determine whether the statement "a chiral carbon consists of 4 different groups attached" is true or false, we can follow these steps:

### Step 1: Understand the Definition of Chiral Carbon
A chiral carbon atom is defined as a carbon atom that is bonded to four different groups or atoms. This unique arrangement allows for the existence of non-superimposable mirror images, known as enantiomers.

**Hint:** Remember that chirality is related to the arrangement of atoms around a carbon atom.

### Step 2: Analyze the Statement
The statement claims that a chiral carbon consists of four different groups attached. Since the definition of a chiral carbon specifically states that it must be attached to four different groups, we can conclude that the statement is correct.

**Hint:** Think about the implications of having identical groups attached to a carbon atom and how that affects chirality.

### Step 3: Consider Examples
For instance, consider a carbon atom attached to the following groups: CH3 (methyl), Cl (chlorine), Br (bromine), and H (hydrogen). This carbon is indeed chiral because all four groups are different.

Conversely, if a carbon is attached to two identical groups (e.g., H, H, CH3, and Br), it cannot be chiral because it does not meet the requirement of having four different groups.

**Hint:** Visualize the molecular structure to see how the groups are arranged around the carbon atom.

### Conclusion
Based on the definition and analysis, we can conclude that the statement is **True**.

**Final Answer:** True
