Which molecule are planar
1.NF3
2.Ccl4
3.C3H6
C3H8
Well, let's take a closer look at each of these molecules through my comedic lens:
1. NF3: Sorry, but this molecule is not planar. It's like trying to balance a unicycle on a tightrope while juggling flaming torches. The nitrogen atom in NF3 has one lone pair of electrons, which creates an electron pair repulsion that pushes the fluorine atoms out of the same plane.
2. CCl4: Ah, my feet are firmly planted on the ground with this one! CCl4, also known as carbon tetrachloride, is indeed a planar molecule. It's as flat as a pancake, or as flat as a bad joke that falls flat.
3. C3H6: Sorry to burst your bubble, but this molecule is not planar either. The carbon atoms in C3H6 are arranged in a cyclopropane ring, creating a three-dimensional puckered shape. It's like trying to fit a square peg into a round hole, or trying to make a balloon giraffe out of square balloons.
4. C3H8: Nope, not planar either. C3H8, also known as propane, is a three-dimensional molecule. It's like trying to play a game of Twister with your molecules. The three carbon atoms in propane are bonded to each other in a zigzag shape, which gives it a non-planar structure.
So, the only molecule that fits the bill here is CCl4. It's as flat as a pancake or a clown slipping on a banana peel.
Out of the given molecules, below are the planar molecules:
1. NF3 - Not planar: NF3 has a pyramidal shape with the nitrogen atom being the central atom and three fluorine atoms surrounding it.
2. CCl4 - Not planar: CCl4 has a tetrahedral shape, where the carbon atom is the central atom bonded to four chlorine atoms.
3. C3H6 - Planar: C3H6, also known as propene, has a planar shape. It consists of three carbon atoms bonded together with a double bond between two of the carbon atoms and single bonds between the other two carbon atoms and hydrogen atoms.
4. C3H8 - Not planar: C3H8, also known as propane, has a tetrahedral shape. It consists of three carbon atoms bonded together with single bonds and hydrogen atoms attached to each carbon atom.
Therefore, among the given molecules, C3H6 is planar.
To determine which molecules are planar, we need to examine their molecular geometry and bond angles.
1. NF3 (Nitrogen trifluoride): NF3 has a trigonal pyramidal molecular geometry. It consists of the central nitrogen atom bonded to three fluorine atoms. The lone pair of electrons on the nitrogen atom causes distortion in the shape, giving it a trigonal pyramidal geometry. Therefore, NF3 is not a planar molecule.
2. CCl4 (Carbon tetrachloride): CCl4 has a tetrahedral molecular geometry. It consists of the central carbon atom bonded to four chlorine atoms. The bond angles are approximately 109.5 degrees, making it a tetrahedral molecule. Therefore, CCl4 is not a planar molecule.
3. C3H6 (Propene): C3H6 has a trigonal planar molecular geometry. It consists of three carbon atoms bonded together in a chain, with each carbon atom bonded to hydrogen atoms. The molecular geometry around each carbon atom is trigonal planar, where the bond angles are approximately 120 degrees. Therefore, C3H6 is a planar molecule.
4. C3H8 (Propane): C3H8 has a tetrahedral molecular geometry. It consists of three carbon atoms bonded together in a chain, with each carbon atom bonded to hydrogen atoms. The molecular geometry around each carbon atom is tetrahedral, where the bond angles are approximately 109.5 degrees. Therefore, C3H8 is not a planar molecule.
In summary, out of the given molecules, C3H6 (Propene) is the only molecule that is planar.
NF3 is not planar.
CCl4 is not planar.
C3H6 is an alkene and the C=C part is planar but the other CH3 portion is not.
