The shape of a molecule surrounding a central atom is determined by the arrangement of its bonding and non-bonding electron pairs, according to the VSEPR (Valence Shell Electron Pair Repulsion) theory. For example, if there are two bonding pairs and no lone pairs, the shape will be linear. With four bonding pairs, the shape becomes tetrahedral. The presence of lone pairs can alter these shapes, leading to variations like trigonal pyramidal or bent geometries.
What else can I help you with?
A molecule that has a central atom surrounded by three single bond pairs and one unshared pair would have a shape.?
The shape would tend to be trigonal pyramidal. An example would be ammonia, NH3.
Is HCI tetrahedral?
No, HCI is not tetrahedral. The molecular shape of hydrogen chloride (HCl) is linear due to the two atoms in the molecule. A tetrahedral shape would have four atoms bonded to a central atom.
What type of bonding around a central atom would result in a triagonal planar molecule?
A trigonal planar molecule results from sp² hybridization around a central atom, where it forms three sigma bonds with surrounding atoms. This arrangement occurs when there are three bonding pairs and no lone pairs of electrons. The bond angles are approximately 120 degrees, creating a flat, triangular shape. Examples of trigonal planar molecules include boron trifluoride (BF₃) and ethylene (C₂H₄).
What shape would a molecule of hydrogen sulfide have?
A molecule of hydrogen sulfide (H2S) would have a bent shape due to its molecular geometry. It consists of two hydrogen atoms bonded to a sulfur atom with lone pairs of electrons around the sulfur, causing the molecule to bend.
A molecule that has a central atom surrounded by three single bond pairs and unshared pair would have a?
A molecule with a central atom surrounded by three single bond pairs and one unshared pair of electrons would have a trigonal pyramidal geometry. This arrangement results from the repulsion between the bonding pairs and the lone pair, leading to a shape that is similar to tetrahedral but slightly distorted due to the presence of the lone pair. An example of such a molecule is ammonia (NH₃).
What shape would a molecule with four atom surrounding a central atom have?
A tetrahedron.
VSEPR formulas would predict a tetrahedral shape?
The VSEPR (Valence Shell Electron Pair Repulsion) theory predicts the geometric shape of a molecule based on the repulsion between electron pairs surrounding the central atom. In a molecule with four electron pairs around the central atom, the VSEPR formula would predict a tetrahedral shape, where the bond angles are approximately 109.5 degrees.
What would cause the shape of the molecule to be tetrahedral?
Four atoms bound to a central atom with no lone pairs
What would cause the shape of a molecule to be tetrahedral?
A molecule with four bonded atoms and no lone pairs on the central atom will have a tetrahedral shape. This occurs when the central atom is bonded to four other atoms, resulting in equal distances between the atoms, leading to a tetrahedral shape due to the arrangement of electron pairs around the central atom.
The shape of ammonia molecule?
It is Triangular pyramid It would be a trigonal pyramidal.
A molecule that has a central atom surrounded by three single bond pairs and one unshared pair would have a shape.?
The shape would tend to be trigonal pyramidal. An example would be ammonia, NH3.
Which of the following configurations would form a bent molecule?
a molecule with two bound atoms and one lone electron pair -apex
Is HCI tetrahedral?
No, HCI is not tetrahedral. The molecular shape of hydrogen chloride (HCl) is linear due to the two atoms in the molecule. A tetrahedral shape would have four atoms bonded to a central atom.
What is the shape of a molecule of sulfur tetrafluoride?
Tetrahedral. Actually, the molecular shape or geometry is called see-saw. There are five groups around the central sulfur which would make it trigonal bipyramidyl but one of these groups is a pair of electrons which does not contribute to the shape of the molecule. This lone pair is in the three membered ring in order to increase its separation from two of the fluorine-sulfur bonds.
What shape would a molecule with two bound groups and two lone pairs have?
The correct answer is: Bent.
What is the molecular shape around the central atom in CF2Cl2?
The molecule that you describe, which would more accurately be written as CCl2F2 is the same shape as a methane molecule; the carbon is in the center, and it is surrounded by a symmetrical arrangement of two chlorine and two fluorine atoms, which are at the points of a tetrahedron.
In the following ions the first atom listed is the center atom to the rest of the atoms. Which of the following ions would have a tetrahedral shape apex?
An ion with a tetrahedral shape apex would have a central atom bonded to four surrounding atoms. Examples include methane (CH₄), with carbon as the central atom, and ammonia (NH₃), with nitrogen as the central atom.
